22.3.2 Viewing IEEE802.3ah/OAM Info

To display IEEE 802.3ah/OAM information, use the show efmoam operation command. The show efmoam command displays the IEEE 802.3ah/OAM configuration information and information about the ports in active mode. The show efmoam detail command displays information about the ports in passive mode that recognize the remote device in addition to the active-mode ports. The show efmoam statistics command displays the status of failures detected by the IEEE 802.3ah/UDLD functionality in addition to IEEE 802.3ah/OAM protocol statistics.
