Priority Mapping for SAP Down MEPs

For SAP Down MEPs, priority mapping operates as described in the following list, which

indicates how the messages or replies generated on egress have their FC and VLAN tag

priority set.

CCMs generated on egress are based on ccm-ltm-prio of the MEP (that is, FC

and VLAN tag priority are set according to the ccm-ltm-prio of the MEP).

LMM, DMM and DM1 generated on egress are based on the priority specified

during the test (that is, FC and VLAN tag priority are set according to the priority

specified during the test).

LMR and DMR generated on egress use the ccm-ltm-prio of the MEP as FC.

The VLAN tag priority is not replaced (that is, the VLAN tag priority of LMM and

DMM are kept).
