MIB MODULE DETAILS RFC1213-MIB

Registration: 1.3.6.1.2.1.1.1 Access: read-only Reference: None Description:

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. It is mandatory that this only contain
printable ASCII characters.

sysObjectID

Registration: 1.3.6.1.2.1.1.2 Access: read-only Reference: None Description:

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
kind of box' is being managed. For example, if
vendor `Flintstones, Inc.' was assigned the
subtree 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'.

sysUpTime

Registration: 1.3.6.1.2.1.1.3 Access: read-only Reference: None Description:

The time (in hundredths of a second) since the
network management portion of the system was last
re-initialized.

sysContact

Registration: 1.3.6.1.2.1.1.4 Access: read-write Reference: None Description:

The textual identification of the contact person
for this managed node, together with information
on how to contact this person.

sysName

Registration: 1.3.6.1.2.1.1.5 Access: read-write Reference: None Description:

An administratively-assigned name for this
managed node. By convention, this is the node's
fully-qualified domain name.

sysLocation

Registration: 1.3.6.1.2.1.1.6 Access: read-write Reference: None Description:

The physical location of this node (e.g.,
`telephone closet, 3rd floor').

sysServices

Registration: 1.3.6.1.2.1.1.7 Access: read-only Reference: None Description:

A value which indicates the set of services that
this entity primarily offers.

The value is a sum. This sum initially takes the
value zero, Then, for each layer, L, in the range
1 through 7, that this node performs transactions
for, 2 raised to (L - 1) is added to the sum. For
example, a node which performs primarily routing
functions would have a value of 4 (2^(3-1)). In
contrast, a node which is a host offering
application services would have a value of 72
(2^(4-1) + 2^(7-1)). Note that in the context of
the Internet suite of protocols, values should be
calculated accordingly:

layer functionality
1 physical (e.g., repeaters)
2 datalink/subnetwork (e.g., bridges)
3 internet (e.g., IP gateways)
4 end-to-end (e.g., IP hosts)
7 applications (e.g., mail relays)

For systems including OSI protocols, layers 5 and
6 may also be counted.

their current state) present on this system.

ifIndex

Registration: 1.3.6.1.2.1.2.2.1.1 Access: read-only Reference: None Description:

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 re-initialization of the entity's
network management system to the next re-
initialization.

ifDescr

Registration: 1.3.6.1.2.1.2.2.1.2 Access: read-only Reference: None Description:

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.

ifType

Registration: 1.3.6.1.2.1.2.2.1.3 Access: read-only Reference: None Description:

The type of interface, distinguished according to
the physical/link protocol(s) immediately `below'
the network layer in the protocol stack.

on the interface.

ifSpeed

Registration: 1.3.6.1.2.1.2.2.1.5 Access: read-only Reference: None Description:

An estimate of the interface's current bandwidth
in bits per second. For interfaces which do not
vary in bandwidth or for those where no accurate
estimation can be made, this object should contain
the nominal bandwidth.

ifPhysAddress

Registration: 1.3.6.1.2.1.2.2.1.6 Access: read-only Reference: None Description:

The interface's address at the protocol layer
immediately `below' the network layer in the
protocol stack. For interfaces which do not have

should contain an octet string of zero length.

ifAdminStatus

Registration: 1.3.6.1.2.1.2.2.1.7 Access: read-write Reference: None Description:

The desired state of the interface. The
testing(3) state indicates that no operational
packets can be passed.

ifOperStatus

Registration: 1.3.6.1.2.1.2.2.1.8 Access: read-only Reference: None Description:

The current operational state of the interface.
The testing(3) state indicates that no operational
packets can be passed.

ifLastChange

Registration: 1.3.6.1.2.1.2.2.1.9 Access: read-only Reference: None Description:

The value of sysUpTime at the time the interface
entered its current operational state. If the
current state was entered prior to the last re-
initialization of the local network management
subsystem, then this object contains a zero
value.

Registration: 1.3.6.1.2.1.2.2.1.13 Access: read-only Reference: None Description:

The number of inbound packets which were 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.

ifInErrors

Registration: 1.3.6.1.2.1.2.2.1.14 Access: read-only Reference: None Description:

The number of inbound packets that contained
errors preventing them from being deliverable to a
higher-layer protocol.

ifInUnknownProtos

Registration: 1.3.6.1.2.1.2.2.1.19 Access: read-only Reference: None Description:

The number of outbound packets which 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.

ifOutErrors

Registration: 1.3.6.1.2.1.2.2.1.20 Access: read-only Reference: None Description:

The number of outbound packets that could not be
transmitted because of errors.

ifOutQLen

Registration: 1.3.6.1.2.1.2.2.1.21 Access: read-only Reference: None Description:

The length of the output packet queue (in
packets).

ifSpecific

Registration: 1.3.6.1.2.1.2.2.1.22 Access: read-only Reference: None Description:

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 syntatically valid
object identifier, and any conformant
implementation of ASN.1 and BER must be able to
generate and recognize this value.

atIfIndex

Registration: 1.3.6.1.2.1.3.1.1.1 Access: read-write Reference: None Description:

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.

atPhysAddress

Registration: 1.3.6.1.2.1.3.1.1.2 Access: read-write Reference: None Description:

The media-dependent `physical' address.

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 dissasociates 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

Registration: 1.3.6.1.2.1.3.1.1.3 Access: read-write Reference: None Description:

The NetworkAddress (e.g., the IP address)
corresponding to the media-dependent `physical'
address.

ipForwarding

Registration: 1.3.6.1.2.1.4.1 Access: read-write Reference: None Description:

The indication of whether this entity is acting
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).

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

Registration: 1.3.6.1.2.1.4.2 Access: read-write Reference: None Description:

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 transport layer protocol.

ipInReceives

Registration: 1.3.6.1.2.1.4.3 Access: read-only Reference: None Description:

The total number of input datagrams received from
interfaces, including those received in error.

ipInHdrErrors

Registration: 1.3.6.1.2.1.4.4 Access: read-only Reference: None Description:

The number of input datagrams discarded due to
errors in their IP headers, including bad
checksums, version number mismatch, other format
errors, time-to-live exceeded, errors discovered
in processing their IP options, etc.

ipInAddrErrors

Registration: 1.3.6.1.2.1.4.5 Access: read-only Reference: None Description:

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 (e.g., 0.0.0.0) and addresses of
unsupported Classes (e.g., Class E). For entities
which are not IP Gateways and therefore do not
forward datagrams, this counter includes datagrams
discarded because the destination address was not
a local address.

ipForwDatagrams

Registration: 1.3.6.1.2.1.4.6 Access: read-only Reference: None Description:

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 which do not act as IP Gateways, this
counter will include only those packets which were
Source-Routed via this entity, and the Source-
Route option processing was successful.

ipInUnknownProtos

Registration: 1.3.6.1.2.1.4.7 Access: read-only Reference: None Description:

The number of locally-addressed datagrams
received successfully but discarded because of an
unknown or unsupported protocol.

ipInDiscards

Registration: 1.3.6.1.2.1.4.8 Access: read-only Reference: None Description:

The number of input IP datagrams for which no
problems were encountered to prevent their
continued processing, but which were discarded
(e.g., for lack of buffer space). Note that this
counter does not include any datagrams discarded
while awaiting re-assembly.

ipInDelivers

Registration: 1.3.6.1.2.1.4.9 Access: read-only Reference: None Description:

The total number of input datagrams successfully
delivered to IP user-protocols (including ICMP).

ipOutRequests

Registration: 1.3.6.1.2.1.4.10 Access: read-only Reference: None Description:

The total number of IP datagrams which 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.

ipOutDiscards

Registration: 1.3.6.1.2.1.4.11 Access: read-only Reference: None Description:

The number of output IP datagrams for which no
problem was encountered to prevent their
transmission to their destination, but which were
discarded (e.g., for lack of buffer space). Note
that this counter would include datagrams counted
in ipForwDatagrams if any such packets met this
(discretionary) discard criterion.

ipOutNoRoutes

Registration: 1.3.6.1.2.1.4.12 Access: read-only Reference: None Description:

The number of IP datagrams discarded because no
route could be found to transmit them to their
destination. Note that this counter includes any
packets counted in ipForwDatagrams which meet this
`no-route' criterion. Note that this includes any
datagarms which a host cannot route because all of
its default gateways are down.

ipReasmTimeout

Registration: 1.3.6.1.2.1.4.13 Access: read-only Reference: None Description:

The maximum number of seconds which received
fragments are held while they are awaiting
reassembly at this entity.

ipReasmReqds

to be reassembled at this entity.

ipReasmOKs

Registration: 1.3.6.1.2.1.4.15 Access: read-only Reference: None Description:

The number of IP datagrams successfully re-
assembled.

ipReasmFails

Registration: 1.3.6.1.2.1.4.16 Access: read-only Reference: None Description:

The number of failures detected by the IP re-
assembly algorithm (for whatever reason: timed
out, errors, etc). 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.

ipFragOKs

Registration: 1.3.6.1.2.1.4.17 Access: read-only Reference: None Description:

The number of IP datagrams that have been
successfully fragmented at this entity.

ipFragFails

Registration: 1.3.6.1.2.1.4.18 Access: read-only Reference: None Description:

The number of IP datagrams that have been
discarded because they needed to be fragmented at
this entity but could not be, e.g., because their
Don't Fragment flag was set.

The number of IP datagram fragments that have
been generated as a result of fragmentation at
this entity.

The IP address to which this entry's addressing
information pertains.

ipAdEntIfIndex

Registration: 1.3.6.1.2.1.4.20.1.2 Access: read-only Reference: None Description:

The index value which uniquely identifies the
interface to which this entry is applicable. The
interface identified by a particular value of this
index is the same interface as identified by the
same value of ifIndex.

ipAdEntNetMask

Registration: 1.3.6.1.2.1.4.20.1.3 Access: read-only Reference: None Description:

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.

ipAdEntBcastAddr

Registration: 1.3.6.1.2.1.4.20.1.4 Access: read-only Reference: None Description:

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.

ipAdEntReasmMaxSize

Registration: 1.3.6.1.2.1.4.20.1.5 Access: read-only Reference: None Description:

The size of the largest IP datagram which this
entity can re-assemble from incoming IP fragmented
datagrams received on this interface.

ipRouteDest

Registration: 1.3.6.1.2.1.4.21.1.1 Access: read-write Reference: None Description:

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
management protocol in use.

ipRouteIfIndex

Registration: 1.3.6.1.2.1.4.21.1.2 Access: read-write Reference: None Description:

The index value which 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.

ipRouteMetric1

Registration: 1.3.6.1.2.1.4.21.1.3 Access: read-write Reference: None Description:

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.

ipRouteMetric2

Registration: 1.3.6.1.2.1.4.21.1.4 Access: read-write Reference: None Description:

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.

ipRouteMetric3

Registration: 1.3.6.1.2.1.4.21.1.5 Access: read-write Reference: None Description:

ipRouteMetric4

Registration: 1.3.6.1.2.1.4.21.1.6 Access: read-write Reference: None Description:

ipRouteNextHop

Registration: 1.3.6.1.2.1.4.21.1.7 Access: read-write Reference: None Description:

The IP address of the next hop of this route.
(In the case of a route bound to an interface
which is realized via a broadcast media, the value
of this field is the agent's IP address on that
interface.)

ipRouteType

Registration: 1.3.6.1.2.1.4.21.1.8 Access: read-write Reference: None Description:

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.

Setting this object to the value invalid(2) has
the effect of invalidating the corresponding entry
in the ipRouteTable object. That is, it
effectively dissasociates 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

Registration: 1.3.6.1.2.1.4.21.1.9 Access: read-only Reference: None Description:

The routing mechanism via which this route was
learned. Inclusion of values for gateway routing
protocols is not intended to imply that hosts
should support those protocols.

ipRouteAge

Registration: 1.3.6.1.2.1.4.21.1.10 Access: read-write Reference: None Description:

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.

ipRouteMask

Registration: 1.3.6.1.2.1.4.21.1.11 Access: read-write Reference: None Description:

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 support arbitrary subnet masks, an
agent constructs the value of the ipRouteMask by
determining whether the value of the correspondent
ipRouteDest field belong 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.

ipRouteMetric5

Registration: 1.3.6.1.2.1.4.21.1.12 Access: read-write Reference: None Description:

ipRouteInfo

Registration: 1.3.6.1.2.1.4.21.1.13 Access: read-only Reference: None Description:

A reference to MIB definitions specific to the
particular routing protocol which is 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 syntatically valid object identifier, and any
conformant implementation of ASN.1 and BER must be
able to generate and recognize this value.

ipNetToMediaIfIndex

Registration: 1.3.6.1.2.1.4.22.1.1 Access: read-write Reference: None Description:

The interface on which this entry's equivalence
is effective. The interface identified by a
particular value of this index is the same

dependent `physical' address.

ipNetToMediaType

Registration: 1.3.6.1.2.1.4.22.1.4 Access: read-write Reference: None Description:

The type of mapping.

Setting this object to the value invalid(2) has
the effect of invalidating the corresponding entry
in the ipNetToMediaTable. That is, it effectively
dissasociates 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.

ipRoutingDiscards

Registration: 1.3.6.1.2.1.4.23 Access: read-only Reference: None Description:

The number of routing entries which were chosen
to be discarded even though they are valid. One
possible reason for discarding such an entry could
be to free-up buffer space for other routing
entries.

Registration: 1.3.6.1.2.1.5.15 Access: read-only Reference: None Description:

The number of ICMP messages which this entity did
not send due to problems discovered within ICMP
such as a lack of buffers. This value should not
include errors discovered outside the ICMP layer
such as the inability of IP to route the resultant
datagram. In some implementations there may be no
types of error which contribute to this counter's
value.

The state of this TCP connection.

The only value which 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,
resulting in immediate termination of the
connection.

As an implementation-specific option, a RST
segment may be sent from the managed node to the
other TCP endpoint (note however that RST segments
are not sent reliably).

tcpConnLocalAddress

initiated Start and Stop events. When read, this
variable always returns the most recent value that
egpNeighEventTrigger was set to. If it has not
been set since the last initialization of the
network management subsystem on the node, it
returns a value of `stop'.

When set, this variable causes a Start or Stop
event on the specified neighbor, as specified on

causes an Idle peer to begin neighbor acquisition
and a non-Idle peer to reinitiate neighbor
acquisition. A stop event causes a non-Idle peer
to return to the Idle state until a Start event
occurs, either via egpNeighEventTrigger or
otherwise.
