Module: COPS-CLIENT-MIB

OID (symbolic): COPS-CLIENT-MIB::copsClientErrLengthMismatch

OID (numeric): 1.3.6.1.2.1.89.1.2.1.1.21

Node type: OBJECT-TYPE

Type: Counter32

Access: read-only

This value is cumulative since agent restart and is not zeroed on new connections.

What is copsClientErrLengthMismatch?

This read-only Counter32, cumulative since agent restart, counts received messages whose declared COPS Message Length didn't match the actual received message size. This suggests message corruption or truncation, potentially from a network path issue between client and server. For example, an admin investigates a rising copsClientErrLengthMismatch as a possible sign of packet fragmentation problems between the client and its PDP.

Examples

Walk all instances (SNMPv2c):

snmpwalk -v2c -c public <target> 1.3.6.1.2.1.89.1.2.1.1.21
snmpwalk -v2c -c public <target> COPS-CLIENT-MIB::copsClientErrLengthMismatch

Get a specific instance (index 1):

snmpget -v2c -c public <target> 1.3.6.1.2.1.89.1.2.1.1.21.1
snmpget -v2c -c public <target> COPS-CLIENT-MIB::copsClientErrLengthMismatch.1
