Description: MAC address returned in the ingress MAC address field. If the dot1agCfmLtrIngress object contains the value ingNoTlv(0), then the contents of this object are meaningless.

What is dot1agCfmLtrIngressMac?

This OID stores the MAC address of the switch port where a Linktrace message entered the network during Ethernet OAM diagnostics. It identifies the ingress point when tracing connectivity paths through a bridged network. An operator would examine this to confirm which switch is receiving their diagnostic packets during end-to-end connectivity troubleshooting.

Examples
