Restrictions for CFM Configuration over EFP Interface with
Cross Connect Feature
•
Configuration of CCM sampling rate for the offloaded sessions using offload sampling command is
not supported.
•
Parsing multiple organizational-specific Type Length Value (TLV) is not supported.
•
Priority-tagged encapsulation type is not supported.
•
CFM Traceroute with (forwarding database) FDB only option is not supported on Up MEP.
•
CFM CC/Ping/Traceroute for Down MEP, CFM Ping/Traceroute for Up MEP use the bypass EAID, so
these packets cannot be mirrored in the egress direction. Only Up MEP CFM CC can be mirrored.
•
CFM Traceroute to expired RMEPSs are flooded only to port where it was last learned. CFM Traceroute
for new RMEPs are not initiated on their own. However ping to both expired and new RMEPs are flooded
to all EFPs in the BD.
