• West/East Port MEP – Specifies the CFM MEPs used to monitor the link on a ring node.
(Range: 1-8191)
To ensure complete monitoring of a ring node, specify the CFM MEPs used to monitor both the
east and west ports of the ring node.
If CFM MEPs are used to monitor the link status of an ERPS node with CFM continuity check
messages, then the MEG Level must match the authorized maintenance level of the CFM
domain to which the specified MEP belongs (see “Configuring CFM Maintenance Domains” on
page 977).
If CFM determines that a MEP node which has been configured to monitor a ring port has gone
down, this information is passed to ERPS, which in turn processes it as a ring node failure.
