Continuity Check Operations
– 703 –
◆
If a maintenance point receives a CCM with an invalid MEPID or MA level or an
MA level lower than its own, a failure is registered which indicates a
configuration error or cross-connect error (i.e., overlapping MAs).
Example
This example enables continuity check messages for the specified maintenance
association.
Console(config)#ethernet cfm cc enable md voip ma rd
Console(config)#
snmp-server enable
traps ethernet cfm cc
This command enables SNMP traps for CFM continuity check events. Use the no
form to disable these traps.
Syntax
[ no ] snmp-server enable traps ethernet cfm cc [ config | loop | mep-down |
mep-up ]
config – Sends a trap if this device receives a CCM with the same MPID as its
own but with a different source MAC address, indicating that a CFM
configuration error exists.
loop – Sends a trap if this device receives a CCM with the same source MAC
address and MPID as its own, indicating that a forwarding loop exists.
mep-down – Sends a trap if this device loses connectivity with a remote
MEP, or connectivity has been restored to a remote MEP which has
recovered from an error condition.
mep-up – Sends a trap if a remote MEP is discovered and added to the local
database, the port state of a previously discovered remote MEP changes, or
a CCM is received from a remote MEP which as an expired entry in the
archived database.
Default Setting
All continuity checks are enabled.
Command Mode
Global Configuration
Command Usage
All mep-up traps are suppressed when cross-checking of MEPs is enabled because
cross-check traps include more detailed status information.
