NAME
mibiisa - Sun SNMP Agent
SYNOPSIS
mibiisa [-ar] [-c config-dir] [-d debug-level] [-p port] [-t
cache-timer]
DESCRIPTION
The mibiisa utility is an RFC 1157-compliant SNMP agent. It
supports MIB-II as defined in RFC 1213, with Sun extensions
under Sun's enterprise number. The MIB (Management Informa-
tion Base) is both readable and writable. The mibiisa util-
ity supports all SNMP protocol operations including GET-
REQUEST, GETNEXT-REQUEST, SET-REQUEST, GET-REPLY, and TRAP.
The mibiisa utility supports the coldStart, linkUp, link-
Down, and authentication traps. The authentication trap may
be disabled by a command-line switch, which itself may be
overridden by a management station writing to a MIB variable
in the standard SNMP MIB group.
The mibiisa utility supports four distinct views of the MIB.
The view used for any request is determined by the community
string contained in that request.
To enhance security, mibiisa supports an option to block all
writes to the MIB. You can also limit the set of management
stations from which the agent will accept requests in the
configuration file used when starting the mibiisa. See the
SECURITY section for more information.
Unless overridden, mibiisa uses UDP port 161, the standard
SNMP port. The mibiisa utility issues traps through the
same port on which it receives SNMP requests.
The mibiisa utility must run with super-user privileges and
is typically started at system startup via /etc/rc3.d.
mibiisa may not be started using inetd(1M). When started,
mibiisa detaches itself from the keyboard, disables all sig-
nals except SIGKILL, SIGILL, SIGUSR1, and SIGUSR2, and
places itself in the background.
OPTIONS
The following options are supported:
-a Disable the generation of authentication traps. How-
ever, an SNMP manager may write a value into snmpEna-
bleAuthenTraps to enable or disable authentication
traps.
-c config-dir
Specify a directory where it expects snmpd.conf file,
on startup. The default directory is /etc/snmp/conf.
-d debug-level
Debug. A value of 0 disables all debug and is the
default. Levels 1 through 3 represent increasing lev-
els of debug output. When mibiisa receives the signal
SIGUSR1, it resets the debug-level to 0. When mibiisa
receives the signal SIGUSR2, it increments the debug-
level by one.
Debug output is sent to the standard output in effect
at the time mibiisa is started. No matter what debug
level is in effect, certain significant events are
logged in the system log.
-p port
Define an alternative UDP port on which mibiisa
listens for incoming requests. The default is UDP
port 161.
-r Place the MIB into read-only mode.
-t cache-timer
By default, information fetched from the kernel is
considered to be valid for 45 seconds from the time it
is retrieved. This cache lifetime may be altered with
this parameter. You cannot set cache-timer to any
value less than 1.
CONFIGURATION FILE
The snmpd.conf file is used for configuration information.
Each entry in the file consists of a keyword followed by a
parameter string. The keyword must begin in the first posi-
tion. Parameters are separated from the keyword and from one
another by white space. Case in keywords is ignored. Each
entry must be contained on a single line. All text following
(and including) a pound sign (#) is ignored. Keywords
currently supported are:
sysdescr
The value to be used to answer queries for sysDescr.
syscontact
The value to be used to answer queries for sysContact.
syslocation
The value to be used to answer queries for sysLoca-
tion.
trap The parameter names one or more hosts to receive
traps. Only five hosts may be listed.
system-group-read-community
The community name to get read access to the system
group and Sun's extended system group.
system-group-write-community
The community name to get write access to the system
group and Sun's extended system group.
read-community
The community name to get read access to the entire
MIB.
write-community
The community name to get write access to the entire
MIB (implies read access).
trap-community
The community name to be used in traps.
kernel-file
The name of the file to use for kernel symbols.
managers
The names of hosts that may send SNMP queries. Only
five hosts may be listed on any one line. This keyword
may be repeated for a total of 32 hosts.
newdevice
The additional devices which are not built in SNMPD.
The format is as follows: newdevice type speed name
where newdevice is the keyword, type is an integer
which has to match your schema file, speed is the new
device's speed, and name is this new device's name.
An example snmpd.conf file is shown below:

INSTALLATION
The mibiisa utility and its configuration file, snmpd.conf,
may be placed in any directory. However for Solaris 2.4 and
subseqent releases, use /usr/lib/snmp for mibiisa itself and
/etc/snmp/conf for the configuration file. You can modify
the configuration file as appropriate. If you make any
changes to snmpd.conf file keyword values, you must kill and
restart mibiisa for the changes to take effect.
Your /etc/services file (or NIS equivalent) should contain
the following entries:
snmp 161/udp # Simple Network Mgmt Protocol
snmp-trap 162/udp snmptrap # SNMP trap (event) messages
The following is an example for Solaris 2.x:
#
# Start the SNMP agent
#
if [ -f /etc/snmp/conf/snmpd.conf -a -x
/usr/lib/snmp/mibiisa ];
then
/opt/SUNWconn/snm/agents/snmpd
echo 'Starting SNMP-agent.'
SECURITY
SNMP, as presently defined, offers relatively little secu-
rity. The mibiisa utility accepts requests from other
machines, which can have the effect of disabling the network
capabilities of your computer. To limit the risk, the confi-
guration file lets you specify a list of up to 32 manager
stations from which mibiisa will accept requests. If you do
not specify any such manager stations, mibiisa accepts
requests from anywhere.
The mibiisa utility also allows you to mark the MIB as
"read-only" by using the -r option.
Finally, mibiisa supports four different community strings.
These strings, however, are visible in the configuration
file and within the SNMP packets as they flow on the net-
work.
The configuration file should be owned by, and readable only
by super-user. In other words the mode should be:
-rw------- 1 root 2090 Oct 17 15:04 /etc/snmp/conf/snmpd.conf
MIB
This section discusses some of the differences between the
mibiisa MIB and the standard MIB-II (as defined in RFC
1213).
The following variables are read-only in the mibiisa MIB:
sysName
atIfIndex
ipDefaultTTL
These variables are read-write in the standard MIB-II.
The mibiisa MIB Address Translation tables support limited
write access: only atPhysAddress may be written, either to
change the physical address of an existing entry or to
delete an entire ARP table entry.
The mibiisa MIB IP Net to Media table supports limited write
access: only ipNetToMediaPhysAddress and ipNetToMediaType
may be written, either to change the physical address of an
existing entry or to delete an entire ARP table entry.
The following variables are read-write in the mibiisa MIB;
however, these variables have fixed values. Any new values
"set" to them are accepted, but have no effect:
ipRoutIfIndex
ipRouteMetric1
ipRouteMetric2
ipRouteMetric3
ipRouteMetric4
ipRouteType
ipRouteAge
ipRouteMask
ipRouteMetric5
The following mibiisa MIB variable reflects the actual state
of the related table entry. "Sets" are accepted but have no
effect:
tcpConnState
The following mibiisa MIB variables are readable, but return
a fixed value:
icmpInDestUnreachs Returns 1
icmpInTimeExcds Returns 1
icmpInParmProbs Returns 1
icmpInSrcQuenchs Returns 1
icmpInRedirects Returns 1

ifInNUcastPkts Returns 0
ifInDiscards Returns 0
ifOutOctets Returns 0
ifOutNUcastPkts Returns 0
ifOutDiscards Returns 0
SCHEMA ATTRIBUTES
The following describes the attributes in the group and
table definitions in the /var/snmp/mib/sun.mib file.
system
The system group reports statistics about a particular sys-
tem (for example, a workstation or a printer).
sysDescr - A textual description of the entity. This value
should include the full name and version identification of
the system's hardware type, software operating-system, and
networking software. This value must only contain printable
ASCII characters. (string[255])
sysObjectID - The vendor's authoritative identification of
the network management subsystem contained in the entity.
This value is allocated within the SMI enterprises subtree
(1.3.6.1.4.1) and provides an easy and unambiguous means for
determining what type of equipment is being managed. For
example, if vendor "Flintstones, Inc." was assigned the sub-
tree 1.3.6.1.4.1.4242, it could assign the identifier
1.3.6.1.4.1.4242.1.1 to its "Fred Router." (objectid)
sysUpTime - Time (in hundredths of a second) since the net-
work management portion of the system was last reinitial-
ized. (timeticks)
sysContact - The textual identification of the contact per-
son for this managed node, together with information on how
to contact this person. (string[255])
sysName - An administratively-assigned name for this managed
node. By convention, this is the node's fully-qualified
domain name. (string[255])
sysLocation - The physical location of this node (for exam-
ple, "telephone closet, 3rd floor" (string[255]))
sysServices - A value indicating the set of services that
this entity primarily offers. (int) The value is a sum.
This sum initially takes the value zero. Then, for each
layer L in the range 1 through 7 for which this node per-
forms transactions, 2 raised to (L - 1) is added to the sum.
For example, a node that performs primarily routing func-
tions would have a value of 4 (2**(3-1)). In contrast, a
node that is a host offering application services would have
a value of 72 (2**(4-1) + 2**(7-1)). Note that in the con-
text of the Internet suite of protocols, values should be
calculated accordingly:
layer functionality
1 physical (such as repeaters)
2 datalink/subnetwork (such as
bridges)
3 internet (such as IP gateways)
4 end-to-end (such as IP hosts)
7 applications (such as mail relays)
For systems including OSI protocols, Layers 5 and 6 may also
be counted.
interfaces
The interfaces group reports the number of interfaces han-
dled by the agent.
ifNumber - The number of network interfaces, regardless of
their current state, present on this system. (int)
ifTable
The ifTable is a table of interface entries. The number of
entries is given by the value of ifNumber.
ifIndex - A unique value for each interface. Its value
ranges between 1 and the value of ifNumber. The value for
each interface must remain constant at least from one reini-
tialization of the entity's network management system to the
next reinitialization. (int)
ifDescr - A textual string containing information about the
interface. This string should include the name of the
manufacturer, the product name, and the version of the
hardware interface. (string[255])
ifType - The type of interface, distinguished according to
the physical/link protocol(s) immediately below the network
layer in the protocol stack. (enum)
ifMtu - The size of the largest datagram that can be
sent/received on the interface, specified in octets. For
interfaces used for transmitting network datagrams, this is
the size of the largest network datagram that can be sent on
the interface. (int)
ifSpeed - An estimate of the interface's current bandwidth
in bits-per-second. For interfaces that do not vary in
bandwidth, or for those where no accurate estimation can be
made, this object should contain the nominal bandwidth.
(gauge)
if1hysAddress - The interface's address at the protocol
layer immediately below the network layer in the protocol
stack. For interfaces without such an address (for example,
a serial line), this object should contain an octet string
of zero length. (octet[128])
ifAdminStatus - The desired state of the interface. The
testing(3) state indicates that no operational packets can
be passed. (enum)
if OperStatus - The current operational state of the inter-
face. The testing(3) state indicates that no operational
packets can be passed. (enum)
ifLastChange - The value of sysUpTime at the time the inter-
face entered its current operational state. If the current
state was entered prior to the last reinitialization of the
local network management subsystem, then this object con-
tains a zero value. (timeticks)
ifInOctets - The total number of octets received on the
interface, including framing characters. (counter) Returns a
fixed value of 0.
ifInUcastPkts - The number of subnetwork-unicast packets
delivered to a higher-layer protocol. (counter)
ifInNUcastPkts - The number of non-unicast (that is,
subnetwork- broadcast or subnetwork-multicast) packets
delivered to a higher-layer protocol. (counter) Returns a
fixed value of 0.
ifInDiscards - The number of inbound packets chosen to be
discarded, even though no errors had been detected to
prevent their being deliverable to a higher-layer protocol.
One possible reason for discarding such a packet could be to
free up buffer space. (counter) Returns a fixed value of 0.
ifInErrors - The number of inbound packets that contained
errors preventing them from being deliverable to a higher-
layer protocol. (counter)
ifInUnknownProtos - The number of packets received via the
interface that were discarded because of an unknown or
unsupported protocol. (counter) Returns a fixed value of 0.
ifOutOctets - The total number of octets transmitted out of
the interface, including framing characters. (counter)
Returns a fixed value of 0.
ifOutUcastPkts - The total number of packets that higher-
level protocols requested be transmitted to a subnetwork-
unicast address, including those that were discarded or not
sent. (counter)
ifOutNUcastPkts - The total number of packets that higher-
level protocols requested be transmitted to a non- unicast
(that is, a subnetwork-broadcast or subnetwork-multicast)
address, including those that were discarded or not sent.
(counter) Returns a fixed value of 0.
ifOutDiscards - The number of outbound packets that were
chosen to be discarded even though no errors had been
detected to prevent their being transmitted. One possible
reason for discarding such a packet could be to free up
buffer space. (counter) Returns a fixed value of 0.
ifOutErrors - The number of outbound packets that could not
be transmitted because of errors. (counter)
ifOutQLen - The length of the output packet queue (in pack-
ets). (gauge)
ifSpecific - A reference to MIB definitions specific to the
particular media being used to realize the interface. For
example, if the interface is realized by an Ethernet, then
the value of this object refers to a document defining
objects specific to Ethernet. If this information is not
present, its value should be set to the OBJECT IDENTIFIER {
0 0 }, which is a syntactically valid object identifier. Any
conformant implementation of ASN.1 and BER must be able to
generate and recognize this value. (objectid)
atTable
atTable Address Translation tables contain the NetworkAd-
dress to physical address equivalences. Some interfaces do
not use translation tables for determining address
equivalences (for example, DDN-X.25 has an algorithmic
method). If all interfaces are of this type, then the
Address Translation table is empty, that is, has zero
entries.
atIfIndex - The interface on which this entry's equivalence
is effective. The interface identified by a particular
value of this index is the same interface as identified by
the same value of ifIndex. (int)
atPhysAddress - The media-dependent physical address.
(octet[128]) Setting this object to a null string (one of
zero length) has the effect of invaliding the corresponding
entry in the atTable object. That is, it effectively disso-
ciates the interface identified with said entry from the
mapping identified with said entry. It is an
implementation-specific matter as to whether the agent
removes an invalidated entry from the table. Accordingly,
management stations must be prepared to receive tabular
information from agents that corresponds to entries not
currently in use. Proper interpretation of such entries
requires examination of the relevant atPhysAddress object.
atNetAddress - The NetworkAddress (that is, the IP address)
corresponding to the media-dependent physical address.
(netaddress)
ip
The ip group reports statistics about the Internet Protocol
(IP) group.
ipForwarding - The indication of whether this entity is act-
ing as an IP gateway in respect to the forwarding of
datagrams received by, but not addressed to, this entity.
IP gateways forward datagrams. IP hosts do not- except
those source-routed via the host. (enum)
Note that for some managed nodes, this object may take on
only a subset of the values possible. Accordingly, it is
appropriate for an agent to return a "badValue" response if
a management station attempts to change this object to an
inappropriate value.
ipDefaultTTL - The default value inserted into the Time-To-
Live field of the IP header of datagrams originated at this
entity, whenever a TTL value is not supplied by the tran-
sport layer protocol. (int)
ipInReceives - The total number of input datagrams received
from interfaces, including those received in error.
(counter)
ipInHdrErrors - The number of input datagrams discarded due
to errors in their IP headers, including bad checksums, ver-
sion number mismatch, other format errors, time-to-live
exceeded, errors discovered in processing their IP options,
and so on. (counter)
ipInAddrErrors - The number of input datagrams discarded
because the IP address in their IP header's destination
field was not a valid address to be received at this entity.
This count includes invalid addresses (for example, 0.0.0.0)
and addresses of unsupported Classes (for example, Class E).
For entities that are not IP Gateways and therefore do not
forward datagrams, this counter includes datagrams discarded
because the destination address was not a local address.
(counter)
ipForwDatagrams - The number of input datagrams for which
this entity was not their final IP destination, as a result
of which an attempt was made to find a route to forward them
to that final destination. In entities that do not act as IP
Gateways, this counter will include only those packets that
were Source-Routed via this entity, and the Source- Route
option processing was successful. (counter)
ipInUnknownProtos - The number of locally-addressed
datagrams received successfully but discarded because of an
unknown or unsupported protocol. (counter)
ipInDiscards - The number of input IP datagrams for which no
problems were encountered to prevent their continued pro-
cessing, but which were discarded, for example, for lack of
buffer space. Note that this counter does not include any
datagrams discarded while awaiting reassembly. (counter)
ipInDelivers - The total number of input datagrams success-
fully delivered to IP user-protocols (including ICMP).
(counter)
ipOutRequests - The total number of IP datagrams that local
IP user-protocols (including ICMP) supplied to IP in
requests for transmission. Note that this counter does not
include any datagrams counted in ipForwDatagrams. (counter)
ipOutDiscards - The number of output IP datagrams for which
no problem was encountered to prevent their transmission to
their destination, but which were discarded (for example,
for lack of buffer space). Note that this counter would
include datagrams counted in ipForwDatagrams if any such
packets met this (discretionary) discard criterion.
(counter)
ipOutNoRoutes - The number of IP datagrams discarded because
no route could be found to transmit them to their destina-
tion. Note that this counter includes any packets counted
in ipForwDatagrams which meet this "no-route" criterion.
Note that this includes any datagrams that a host cannot
route because all its default gateways are down. (counter)
ipReasmTimeout - The maximum number of seconds that received
fragments are held while they are awaiting reassembly at
this entity. (int)
ipReasmReqds - The number of IP fragments received that
needed to be reassembled at this entity. (counter)
ipReasmOKs - The number of IP datagrams successfully
reassembled. (counter)
ipReasmFails - The number of failures detected by the IP
reassembly algorithm, for whatever reason: timed out,
errors, and the like. Note that this is not necessarily a
count of discarded IP fragments since some algorithms
(notably the algorithm in RFC 815) can lose track of the
number of fragments by combining them as they are received.
(counter)
ipFragOKs - The number of IP datagrams that have been suc-
cessfully fragmented at this entity. (counter)
ipFragFails - The number of IP datagrams that have been dis-
carded because they needed to be fragmented at this entity
but could not be, for example, because their "Don't Frag-
ment" flag was set. (counter)
ipFragCreates - The number of IP datagram fragments that
have been generated as a result of fragmentation at this
entity. (counter)
ipRoutingDiscards - The number of routing entries that were
chosen to be discarded even though they were valid. One
possible reason for discarding such an entry could be to
free-up buffer space for other routing entries. (counter)
Returns a fixed value of 0.
ipAddrTable
ipAddrTable is a table of addressing information relevant to
this entity's IP addresses.
ipAdEntAddr - The IP address to which this entry's address-
ing information pertains. (netaddress)
ipAdEntIfIndex - The index value that uniquely identifies
the interface to which this entry is applicable. The inter-
face identified by a particular value of this index is the
same interface as identified by the same value of ifIndex.
(int)
ipAdEntNetMask - The subnet mask associated with the IP
address of this entry. The value of the mask is an IP
address with all the network bits set to 1, and all the
hosts bits set to 0. (netaddress)
ipAdEntBcastAddr - The value of the least-significant bit in
the IP broadcast address used for sending datagrams on the
(logical) interface associated with the IP address of this
entry. For example, when the Internet standard all-ones
broadcast address is used, the value will be 1. This value
applies to both the subnet and network broadcasts addresses
used by the entity on this (logical) interface. (int)
Returns a fixed value of 1.
ipAdEntReasmMaxSize - The size of the largest IP datagram
that this entity can reassemble from incoming IP fragmented
datagrams received on this interface. (int) Returns a fixed
value of 65535.
ipRouteTable
The ipRouteTable is this entity's IP Routing table.
ipRouteDest - The destination IP address of this route. An
entry with a value of 0.0.0.0 is considered a default route.
Multiple routes to a single destination can appear in the
table, but access to such multiple entries is dependent on
the table- access mechanisms defined by the network manage-
ment protocol in use. (netaddress)
ipRouteIfIndex - The index value that uniquely identifies
the local interface through which the next hop of this route
should be reached. The interface identified by a particular
value of this index is the same interface as identified by
the same value of ifIndex. (int)
ipRouteMetric1 - The primary routing metric for this route.
The semantics of this metric are determined by the routing-
protocol specified in the route's ipRouteProto value. If
this metric is not used, its value should be set to -1.
(int) Returns a fixed value of -1.
ipRouteMetric2 - An alternate routing metric for this route.
The semantics of this metric are determined by the routing-
protocol specified in the route's ipRouteProto value. If
this metric is not used, its value should be set to -1.
(int) Returns a fixed value of -1.
ipRouteMetric3 - An alternate routing metric for this route.
The semantics of this metric are determined by the routing-
protocol specified in the route's ipRouteProto value. If
this metric is not used, its value should be set to -1.
(int) Returns a fixed value of -1.
ipRouteMetric4 - An alternate routing metric for this route.
The semantics of this metric are determined by the routing-
protocol specified in the route's ipRouteProto value. If
this metric is not used, its value should be set to -1.
(int) Returns a fixed value of -1.
ipRouteNextHop - The IP address of the next hop of this
route. (In the case of a route bound to an interface that is
realized via a broadcast media, the value of this field is
the agent's IP address on that interface.) (netaddress)
ipRouteType - The type of route. Note that the values
direct (3) and indirect (4) refer to the notion of direct
and indirect routing in the IP architecture. (enum)
Setting this object to the value invalid (2) has the effect
of invalidating the corresponding entry in the ipRouteTable
object. That is, it effectively dissociates the destination
identified with said entry from the route identified with
said entry. It is an implementation-specific matter as to
whether the agent removes an invalidated entry from the
table. Accordingly, management stations must be prepared to
receive tabular information from agents that corresponds to
entries not currently in use. Proper interpretation of such
entries requires examination of the relevant ipRouteType
object.
ipRouteProto - The routing mechanism through which this
route was learned. Inclusion of values for gateway routing
protocols is not intended to imply that hosts should support
those protocols. (enum)
ipRouteAge - The number of seconds since this route was last
updated or otherwise determined to be correct. Note that no
semantics of "too old" can be implied except through
knowledge of the routing protocol by which the route was
learned. (int) Returns a fixed value of 0.
ipRouteMask - Indicate the mask to be logical-ANDed with the
destination address before being compared to the value in
the ipRouteDest field. For those systems that do not sup-
port arbitrary subnet masks, an agent constructs the value
of the ipRouteMask by determining whether the value of the
correspondent ipRouteDest field belongs to a class-A, B, or
C network, and then using one of:
mask network
255.0.0.0 class-A
255.255.0.0 class-B
255.255.255.0 class-C
If the value of the ipRouteDest is 0.0.0.0 (a default
route), then the mask value is also 0.0.0.0. It should be
noted that all IP routing subsystems implicitly use this
mechanism. (netaddress)
ipRouteMetric5 - An alternate routing metric for this route.
The semantics of this metric are determined by the routing-
protocol specified in the route's ipRouteProto value. If
this metric is not used, its value should be set to -1.
(int) Returns a fixed value of -1.
ipRouteInfo - A reference to MIB definitions specific to the
particular routing protocol responsible for this route, as
determined by the value specified in the route's
ipRouteProto value. If this information is not present, its
value should be set to the OBJECT IDENTIFIER { 0 0 }, which
is a syntactically valid object identifier. Any conformant
implementation of ASN.1 and BER must be able to generate and
recognize this value. (objectid)
ipNetToMediaTable
The ipNetToMediaTable is the IP Address Translation table
used for mapping from IP addresses to physical addresses.
ipNetToMediaIfIndex - The interface on which this entry's
equivalence is effective. The interface identified by a
particular value of this index is the same interface as
identified by the same value of ifIndex. (int)
ipNetToMediaPhysAddress - The media-dependent physical
address. (octet[128])
ipNetToMediaNetAddress - The IpAddress corresponding to the
media- dependent physical address. (netaddress)
ipNetToMediaType - The type of mapping. (enum) Returns a
fixed value of (3)dynamic. Setting this object to the value
invalid(2) has the effect of invalidating the corresponding
entry in the ipNetToMediaTable. That is, it effectively
dissociates the interface identified with said entry from
the mapping identified with said entry. It is an
implementation-specific matter as to whether the agent
removes an invalidated entry from the table. Accordingly,
management stations must be prepared to receive tabular
information from agents that corresponds to entries not
currently in use. Proper interpretation of such entries
requires examination of the relevant ipNetToMediaType
object.
icmp
The icmp group reports statistics about the ICMP group.
icmpInMsgs - The total number of ICMP messages that the
entity received. Note that this counter includes all those
counted by icmpInErrors. (counter)
icmpInErrors - The number of ICMP messages that the entity
received but determined as having ICMP-specific errors (bad
ICMP checksums, bad length, and the like.). (counter)
icmpInDestUnreachs - The number of ICMP Destination Unreach-
able messages received. (counter)

tcp
The tcp group reports statistics about the TCP group.
tcpRtoAlgorithm - The algorithm used to determine the
timeout value used for retransmitting unacknowledged octets.
(enum)
tcpRtoMin - The minimum value permitted by a TCP implementa-
tion for the retransmission timeout, measured in mil-
liseconds. More refined semantics for objects of this type
depend upon the algorithm used to determine the retransmis-
sion timeout. In particular, when the timeout algorithm is
rsre(3), an object of this type has the semantics of the
LBOUND quantity described in RFC 793. (int)
tcpRtoMax - The maximum value permitted by a TCP implementa-
tion for the retransmission timeout, measured in mil-
liseconds. More refined semantics for objects of this type
depend upon the algorithm used to determine the retransmis-
sion timeout. In particular, when the timeout algorithm is
rsre(3), an object of this type has the semantics of the
UBOUND quantity described in RFC 793. (int)
tcpMaxConn - The limit on the total number of TCP connec-
tions that the entity can support. In entities where the
maximum number of connections is dynamic, this object should
contain the value -1. (int)
tcpActiveOpens - The number of times that TCP connections
have made a direct transition to the SYN-SENT state from the
CLOSED state. (counter)
tcpPassiveOpens - The number of times that TCP connections
have made a direct transition to the SYN-RCVD state from the
LISTEN state. (counter)
tcpAttemptFails - The number of times that TCP connections
have made a direct transition to the CLOSED state from
either the SYN-SENT state or the SYN-RCVD state, plus the
number of times TCP connections have made a direct transi-
tion to the LISTEN state from the SYN-RCVD state. (counter)
tcpEstabResets - The number of times TCP connections have
made a direct transition to the CLOSED state from either the
ESTABLISHED state or the CLOSE-WAIT state. (counter)

tcpConnTable
The tcpConnTable is a table containing TCP connection-
specific information.
tcpConnState - The state of this TCP connection. (enum)
The only value that may be set by a management station is
deleteTCB(12). Accordingly, it is appropriate for an agent
to return a "badValue" response if a management station
attempts to set this object to any other value.
If a management station sets this object to the value
deleteTCB(12), then this has the effect of deleting the TCB
(as defined in RFC 793) of the corresponding connection on
the managed node. This results in immediate termination of
the connection.
As an implementation-specific option, an RST segment may be
sent from the managed node to the other TCP endpoint. (Note,
however, that RST segments are not sent reliably.)
tcpConnLocalAddress - The local IP address for this TCP con-
nection. For a connection in the listen state that is wil-
ling to accept connections for any IP interface associated
with the node, the value 0.0.0.0 is used. (netaddress)
tcpConnLocalPort - The local port number for this TCP con-
nection. (int)
tcpConnRemAddress - The remote IP address for this TCP con-
nection. (netaddress)
tcpConnRemPort - The remote port number for this TCP connec-
tion. (int)
upd
The udp group reports statistics about the UDP group.
udpInDatagrams - The total number of UDP datagrams delivered
to UDP users. (counter) Returns a fixed value of 0.
udpNoPorts - The total number of received UDP datagrams for
which there was no application at the destination port.
(counter) Returns a fixed value of 0.
udpInErrors - The number of received UDP datagrams that
could not be delivered for reasons other than the lack of an
application at the destination port. (counter)
udpOutDatagrams - The total number of UDP datagrams sent
from this entity. (counter) Returns a fixed value of 0.
udpTable
The udpTable is a table containing UDP listener information.

status field is "badValue." (counter)
snmpInReadOnlys - The total number valid SNMP PDUs delivered
to the SNMP protocol entity for which the value of the
error-status field is "readOnly." It should be noted that
it is a protocol error to generate an SNMP PDU that contains
the value "readOnly" in the error-status field. This object
is provided as a means of detecting incorrect implementa-
tions of the SNMP. (counter)
snmpInGenErrs - The total number of SNMP PDUs delivered to
the SNMP protocol entity for which the value of the error-

DIAGNOSTICS
cannot dispatch request
The proxy cannot dispatch the request. The rest of
the message indicates the cause of the failure.
select(3C) failed
A select(3C) call failed. The rest of the message
indicates the cause of the failure.
sendto(3SOCKET) failed
A sendto(3SOCKET) call failed. The rest of the mes-
sage indicates the cause of the failure.
recvfrom(3SOCKET) failed
A recvfrom(3SOCKET) call failed. The rest of the
message indicates the cause of the failure.
no response from system
The SNMP agent on the target system does not respond
to SNMP requests. This error might indicate that the
SNMP agent is not running on the target system, the
target system is down, or the network containing the
target system is unreachable.
response too big
The agent could not fit the results of an operation
into a single SNMP message. Split large groups or
tables into smaller entities.
missing attribute
An attribute is missing from the requested group.
bad attribute type
An object attribute type received from the SNMP agent
that does not match the attribute type specified by
the proxy agent schema. The rest of the message indi-
cates the expected type and received type.
cannot get sysUpTime
The proxy agent cannot get the variable sysUpTime from
the SNMP agent.
sysUpTime type bad
The variable sysUpTime received from the SNMP agent
has the wrong data type.
unknown SNMP error
An unknown SNMP error was received.
bad variable value
The requested specified an incorrect syntax or value
for a set operation.
variable is read only
The SNMP agent did not perform the set request because
a variable to set may not be written.
general error
A general error was received.
cannot make request PDU
An error occurred building a request PDU.
cannot make request varbind list
An error occurred building a request variable binding
list.
cannot parse response PDU
An error occurred parsing a response PDU.
request ID - response ID mismatch
The response ID does not match the request ID.
string contains non-displayable characters
A displayable string contains non-displayable charac-
ters.
cannot open schema file
An error occurred opening the proxy agent schema file.
cannot parse schema file
The proxy agent couldn't parse the proxy agent schema
file.
cannot open host file
An error occurred opening the file associated with the
na.snmp.hostfile keyword in /etc/snmp/conf/snmpd.conf
cannot parse host file
The proxy agent was unable to parse the file associ-
ated with the na.snmp.hostfile keyword in
/etc/snmp/conf/snm.conf.
attribute unavailable for set operations
The set could not be completed because the attribute
was not available for set operations.
BUGS
The mibiisa utility returns the wrong interface speed for
the SBUS FDDI interface (for example, "bf0").
The mibiisa utility does not return a MAC address for the
SBUS FDDI interface (for example, "bf0").
Process names retrieved from mibiisa contain a leading
blank space.
When you change attribute values in the system group with an
SNMP set request, the change is effective only as long as
mibiisa is running. mibiisa does not save the changes to
/etc/snmp/conf/snmpd.conf.
