Command Usage
◆ This parameter is used to ensure that received R-APS PDUs are directed for this
instance. A unique level should be configured for each local instance 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.
Example
Console(config-erps)#meg-level 0
