Cisco IOS Release 12.2(33)SRB
No interactions are required between Ethernet LMI and the OAM manager on the CE side. On the
user-facing provider edge (UPE) side, the OAM manager defines an abstraction layer that relays data
collected from Ethernet CFM to the Ethernet LMI device.
user-facing provider edge (UPE) side, the OAM manager defines an abstraction layer that relays data
collected from Ethernet CFM to the Ethernet LMI device.
Ethernet LMI and OAM manager interaction is unidirectional, from the OAM manager to Ethernet LMI
on the UPE side of the device. An information exchange results from an Ethernet LMI request or is
triggered by the OAM manager when the OAM manager receives notification from the OAM protocol
that the EVC status has changed. In this case, the change is called a remote link status change.

Benefits of Remote Port Shutdown
The Remote Port Shutdown feature provides direct interaction of Ethernet LMI with MPLS, LDP, and
OAM. When CFM/802.1ag is not running in a network, Remote Port Shutdown enables communication
of link status to a CE, and traffic from the CE can be stopped if MPLS or the pseudowire is down.
