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" on page 487.
EXAMPLE
Console(config-erps)#mep-monitor east mep 1
