cseL2AddrLearnFailures
Module: CISCO-SWITCH-ENGINE-MIB
OID (symbolic): CISCO-SWITCH-ENGINE-MIB::cseL2AddrLearnFailures
OID (numeric): 1.3.6.1.4.1.9.9.97.1.1.1.1.5
Node type: OBJECT-TYPE
Type: Counter32
Access: read-only
Description: Number of MAC addresses failed to be learned because the L2 forwarding address table was full. If the value keeps increasing, the network topology should be reconfigured.
What is cseL2AddrLearnFailures?
This read-only counter tracks MAC address learning failures caused by a full Layer 2 forwarding address table; a steadily rising value suggests the network topology may need to be reconfigured.
Examples
Walk all instances (SNMPv2c):
