Field Description
Provides information about the physical link; displays one or more
of the following values:
Remote-Stable—Indicates remote OAM client acknowledgment
and acceptance of local OAM state information. False indicates
that remote entity either has not received or remote state
settings do no match local state information. True indicates
that remote entity has received and remote state settings
match local state information
Local-Stable—Indicates local OAM client acknowledgment
and acceptance of remote OAM state information. False
indicates that local entity either has not received or local state
settings do not match remote state information. True indicates
that local entity has received and local state settings match
remote state information
Local-Evaluating—The Local Stable and Local Evaluating bits
of the Flags field communicate the status of the local discovery
process to the peer. When the OAM discovery process is started,
the local entity sets the Local Stable to 0 and Local Evaluating
bits to 1 indicating OAM discovery has not completed. When
Local Stable is set to 1 and Local Evaluating is set to 0 and
Remote Stable is set to 1 and Remote Evaluating is set to 0
indicating that the settings of both the local and remote OAM
clients match, the OAM Discovery process has successfully
completed
Remote-State-Valid—Indicates the OAM client has received
remote state information found within Local Information TLVs
of received Information OAM PDUs. False indicates that OAM
client has not seen remote state information. True indicates
that the OAM client has seen remote state information
State of the loopback functionality of the local and remote OAM
entities; displays one or more of the following values:
Supported—Indicates that the Ethernet OAM configuration on
the interface is configured to initiate remote loopback or
respond to a remote loopback request it receives from a peer.
When you place a remote entity into loopback mode, the
interface receives the remote-loopback request and puts the
interface into remote-loopback mode. When a
remote-loopback request is sent by a remote entity, the local
interface is placed into loopback mode
Local enabled—Indicates that the loopback operation is
enabled on the specified interface of the local OAM entity,
which causes the local entity to loop back the received frames
other than OAM PDUs to the remote peer
Remote enabled—Indicates that the loopback operation is
enabled on the specified interface of the remote peer, which
causes the remote peer to loop back all received frames other
than OAM PDUs to the local OAM entity
