Command Usage
◆
If this command is used to monitor the link status of an ERPS node with CFM
continuity check messages, then the MEG level set by the
meg-level command
must match the authorized maintenance level of the CFM domain to which the
specified MEP belongs.
◆
To ensure complete monitoring of a ring node, use the mep-monitor
command to specify the CFM MEPs used to monitor both the east and west
ports of the ring node.
◆
If CFM determines that a MEP node which has been configured to monitor a
ring port with this command has gone down, this information is passed to
ERPS, which in turn processes it as a ring node failure. For more information on
how ERPS recovers from a node failure, refer to “Ethernet Ring Protection
Switching” in the
Web Management Guide .
Example
Console(config-erps)#mep-monitor east mep 1
