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
