◆ This parameter is used to ensure that received R-APS PDUs are directed
for this ring. A unique level should be configured for each local ring if
there are many R-APS PDUs passing through this switch.
◆ If CFM continuity check messages are used to monitor the link status of
an ERPS ring node as specified by the mep-monitor command, 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. The MEP’s primary VLAN must also be the same as that used
for the ERPS ring’s control VLAN.

◆ 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
