Alcatel-Lucent 7705 - Table 11: FC and VLAN Priority Mappings for up and down Meps as Per Frame Type

Services Overview
7705 SAR OS Services Guide Page 81
• Loss Measurement messages (LMMs), two-way Delay Measurement messages
(DMMs), and one-way Delay Measurement messages (DM1s) generated on ingress
are based on the priority specified during the LMM, DMM, or DM1 test (that is, the
VLAN tag priority is set according to the priority specified during the test).
• Loss Measurement replies (LMRs) and two-way Delay Measurement replies
(DMRs) generated on ingress keep the VLAN tag priority of their corresponding
LMM or DMM frame.
Table 11 summarizes the FC and VLAN priority mappings for SAP Up and Down MEPs
based on the frame type.
