ipForwarding |
.1.3.6.1.2.1.4.1 |
The indication of whether this entity is acting as an IP
router in respect to the forwarding of datagrams received
by, but not addressed to, this entity. IP routers forward
datagrams. IP hosts do not (except those source-routed via
the host).
|
ipDefaultTTL |
.1.3.6.1.2.1.4.2 |
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 |
.1.3.6.1.2.1.4.3 |
The total number of input datagrams received from
interfaces, including those received in error.
|
ipInHdrErrors |
.1.3.6.1.2.1.4.4 |
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 |
.1.3.6.1.2.1.4.5 |
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 routers and therefore do not forward datagrams, this
counter includes datagrams discarded because the destination
address was not a local address.
|
ipForwDatagrams |
.1.3.6.1.2.1.4.6 |
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 routers,
this counter will include only those packets which were
Source-Routed via this entity, and the Source-Route option
processing was successful.
|
ipInUnknownProtos |
.1.3.6.1.2.1.4.7 |
The number of locally-addressed datagrams received
successfully but discarded because of an unknown or
unsupported protocol.
|
ipInDiscards |
.1.3.6.1.2.1.4.8 |
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 |
.1.3.6.1.2.1.4.9 |
The total number of input datagrams successfully delivered
to IP user-protocols (including ICMP).
|
ipOutRequests |
.1.3.6.1.2.1.4.10 |
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 |
.1.3.6.1.2.1.4.11 |
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 |
.1.3.6.1.2.1.4.12 |
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 datagrams which a host cannot route because all
of its default routers are down.
|
ipReasmTimeout |
.1.3.6.1.2.1.4.13 |
The maximum number of seconds which received fragments are
held while they are awaiting reassembly at this entity.
|
ipReasmReqds |
.1.3.6.1.2.1.4.14 |
The number of IP fragments received which needed to be
reassembled at this entity.
|
ipReasmOKs |
.1.3.6.1.2.1.4.15 |
The number of IP datagrams successfully re-assembled.
|
ipReasmFails |
.1.3.6.1.2.1.4.16 |
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 |
.1.3.6.1.2.1.4.17 |
The number of IP datagrams that have been successfully
fragmented at this entity.
|
ipFragFails |
.1.3.6.1.2.1.4.18 |
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.
|
ipFragCreates |
.1.3.6.1.2.1.4.19 |
The number of IP datagram fragments that have been
generated as a result of fragmentation at this entity.
|
ipAddrEntry |
.1.3.6.1.2.1.4.20.1 |
The addressing information for one of this entity's IP
addresses.
|
ipNetToMediaEntry |
.1.3.6.1.2.1.4.22.1 |
Each entry contains one IpAddress to `physical' address
equivalence.
|
ipRoutingDiscards |
.1.3.6.1.2.1.4.23 |
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.
|

received. Note that this counter includes all those counted
by icmpInErrors.

The total number of ICMP messages which this entity
attempted to send. Note that this counter includes all
those counted by icmpOutErrors.
|
icmpOutErrors |
.1.3.6.1.2.1.5.15 |
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 IP address to which this entry's addressing information
pertains.
|
ipAdEntIfIndex |
.1.3.6.1.2.1.4.20.1.2 |
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 RFC 1573's ifIndex.
|
ipAdEntNetMask |
.1.3.6.1.2.1.4.20.1.3 |

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.
|

.1.3.6.1.2.1.4.20.1.4 |
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 |
.1.3.6.1.2.1.4.20.1.5 |
The size of the largest IP datagram which this entity can
re-assemble from incoming IP fragmented datagrams received
on this interface.
|
ipNetToMediaIfIndex |
.1.3.6.1.2.1.4.22.1.1 |
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 RFC 1573's ifIndex.
|
ipNetToMediaNetAddress |

`physical' address.

The media-dependent `physical' address.
|
ipNetToMediaType |
.1.3.6.1.2.1.4.22.1.4 |
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 disassociates
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.
