Field

Description

 

 

ipOutNoRoutes

The number of IP datagrams discarded because no route could be found to trans-

 

mit them to their destination. Note that this counter includes any packets counted

 

in ipForwDatagrams, which meet this no-routecriterion. Note that this

 

includes any datagrams which a host cannot route because all of its default gate-

 

ways are down.

 

 

ipReasmReqds

The number of IP fragments received which needed to be reassembled at this

 

entity (the switch).

 

 

ipReasmOKs

The number of IP datagrams successfully re- assembled.

 

 

ipReasmFails

The number of failures detected by the IP re- assembly algorithm (for whatever

 

reason: timed out, errors, and so forth). 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

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

 

(the switch).

 

 

ipFragFails

The number of IP datagrams that have been discarded because they needed to be

 

fragmented at this entity (the switch) but could not be, for example, because their

 

Don't Fragment flag was set.

ipFragCreates

The number of IP datagram fragments that have been generated as a result of

 

fragmentation at this entity (the switch).

 

 

ipRoutingDiscards

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.

 

 

ipDefaultTTL

The default value inserted into the Time-To-Live(TTL) field of the IP

 

header of datagrams originated at this entity (the switch), whenever a TTL value

 

is not supplied by the transport layer protocol.

 

 

ipReasmTimeout

The maximum number of seconds, which received fragments are held while they

 

are awaiting reassembly at this entity (the switch).
