ieee8021BridgeBasePortMtuExceededDiscards
Module: IEEE8021-BRIDGE-MIB
OID (symbolic): IEEE8021-BRIDGE-MIB::ieee8021BridgeBasePortMtuExceededDiscards
OID (numeric): 1.3.111.2.802.1.1.2.1.1.4.1.5
Node type: OBJECT-TYPE
Type: Counter64
Access: read-only
Description: The number of frames discarded by this port due to an excessive size. It is incremented by both transparent and source route Bridges.
Discontinuities in the value of the counter can occur at re-initialization of the management system, and at other times as indicated by the value of ifCounterDiscontinuityTime object of the associated interface (if any).
What is ieee8021BridgeBasePortMtuExceededDiscards?
Counts frames this port discarded for exceeding the maximum allowed size, useful for spotting an MTU mismatch with a neighboring device.
Examples
Walk all instances (SNMPv2c):
snmpwalk -v2c -c public <target> 1.3.111.2.802.1.1.2.1.1.4.1.5 snmpwalk -v2c -c public <target> IEEE8021-BRIDGE-MIB::ieee8021BridgeBasePortMtuExceededDiscards
Get a specific instance (index 1):
snmpget -v2c -c public <target> 1.3.111.2.802.1.1.2.1.1.4.1.5.1 snmpget -v2c -c public <target> IEEE8021-BRIDGE-MIB::ieee8021BridgeBasePortMtuExceededDiscards.1
