Description
On M7i and M10i routers with Enhanced CFEB (CFEB-E), and on M320, MX Series, ACX Series, T320, and T640 routers, display IEEE 802.1ag Operation, Administration, and Management (OAM) connectivity fault management (CFM) database information for Ethernet interfaces.
In addition, for Ethernet interfaces on MX Series routers , also display any ITU-T Y.1731 frame delay measurement (ETH-DM) frame counts when detail or extensive mode is specified.
For Ethernet interfaces on MX Series routers, display any ITU-T Y.1731 synthetic frame loss measurement (ETH-SLM) statistics and frame counts.
