Modifying the MEP CCM and Linktrace 802.1p Priority

You can modify the 802.1p priority used by connectivity check messages and messages sent by the linktrace protocol. 802.1p CCM and linktrace message priority is on a per MEP basis. Valid values are 0 - 7. The default value is 1. Use the priority command in MEP configuration mode to modify the 802.1p priority used by CCMs and linktrace messages.

The priority command does not affect loopback protocol message 802.1p priority. Loopback protocol message priority can be modified when entering the loopback command.

This example shows how to set set the continuity check message and linkstate message priority for MEP 1000 to 3:

System(rw-config)->cfm md string-name myMD1
System(su-config-cfm-md.1)->ma string-name myMA1
System(su-config-cfm-ma.1)->mep 1000
System(su-config-cfm-mep.1000)->priority 3
System(su-config-cfm-mep.1000)->
