This command was introduced.Release 3.9.1
Usage Guidelines
This command allows you to set the number of tags in CFM packets from up MEPs to 1, so that the system
can differentiate between CFM packets and data packets. When not configured, CFM packets from UP MEPs
have the same number of tags as data packets, and consequently, may not be forwarded to the appropriate
route.
Tags can be configured only for services that are associated with a bridge domain or cross-connect.
