Restrictions for Configuring Multi-UNI CFM MEPs in the Same VPN
•
Two MAs can be configured such that MA2 connected with different BD will act as a proxy (alias) for
MA1 only for the MEPs with service direction as Up.
•
Y1731-PM is not supported with Multi-NNI CFM.
•
The Multi-NNI CFM feature and SLM/DMM over xconnect, Smart SFP, and CFM over xconnect cannot
be configured together.
•
Same customer traffic associated to different BDs should not be configured under a single port.
•
To enable the Multi-NNI CFM, use the platform cfm command, save the configuration, and reboot
your device.
To disable Multi-NNI CFM, use the “no” form of the platform cfm command, save the configuration,
and reboot your device.
•
Toggling the alias command removes the MEPs from the maintenance domain.
