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
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

The ring node identifier is used to identify a node in R-APS messages
◆
for both automatic and manual switching recovery operations.
For example, a node that has one ring port in SF condition and detects
that the condition has been cleared, will continuously transmit R-APS
(NR) messages with its own Node ID as priority information over both
