ipIfStatsReasmFails

Module: IP-MIB

OID (symbolic): IP-MIB::ipIfStatsReasmFails

OID (numeric): 1.3.6.1.2.1.4.31.3.1.16

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

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.

When tracking interface statistics, the counter of the interface to which these fragments were addressed is incremented. This interface might not be the same as the input interface for some of the fragments.

Discontinuities in the value of this counter can occur at re-initialization of the management system, and at other times as indicated by the value of ipIfStatsDiscontinuityTime.

What is ipIfStatsReasmFails?

The number of failures detected by the IP reassembly algorithm on this specific interface (timeouts, errors, etc.); this is not necessarily a count of discarded fragments, since some algorithms lose track of fragment counts as they combine them.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.4.31.3.1.16
snmpwalk -v2c -c public <target> IP-MIB::ipIfStatsReasmFails

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.4.31.3.1.16.1
snmpget -v2c -c public <target> IP-MIB::ipIfStatsReasmFails.1
