Table 5 show ethernet cfm local meps Field Descriptions
ID
|
Configured MEP ID of the MEP.
|
Interface (State)
|
Interface that the MEP is configured under, and the state of the
interface. The states are derived from the interface state, the Ethernet
Link OAM interworking state, and the Spanning Tree Protocol (STP) state.
The following states are reported:
- Up – Interface Up, Ethernet Link OAM Up, STP Up
- Down – Interface Down or Admin Down
- Test – Interface Up, Ethernet Link OAM loopback mode
- Blkd – Interface Up, Ethernet Link OAM Up, STP Blocked
- Otherwise, the interface state.
|
Dir
|
Direction of the MEP.
|
RD
|
Remote Defect. Y (yes) indicates that a remote defect is detected on at
least one peer MEP. In which case, the RDI bit is set in outgoing CCM
messages. Otherwise, N (no).
|
MEPs
|
Total number of peer MEPs sending CCMs to the local MEP.
|
Err
|
Number of peer MEPs for which at least one error has been detected.
|
Defects
|
Types of errors detected. Each error is listed as a single character.
Multiple errors are listed if they are from the same MEP. Possible errors
are listed at the top of the display output of the command.
|
AIS
|
Alarm Indication Signal. If AIS is configured for the service, the
configured level is displayed when an alarm is signaled. If AIS is not
configured for the service, or if no alarm is currently signaled, this
field is blank.
Note
|
In Cisco IOS XR Release 4.0, AIS is not supported, so this field
will always be blank.

This example shows sample output of detailed statistics for
local MEPs:
Note |
The Discarded CCMs field is not displayed when the number is zero
(0). It is unusual for the count of discarded CCMs to be anything other than zero,
since CCMs are only discarded when the limit on the number of peer MEPs is reached.
The Peer MEPs field is always displayed, but the counts are always zero when
continuity check is not enabled.
