Syntax Description This command has no arguments or keywords.

Command Modes Interface configuration (config-if)
Command History
Usage Guidelines This command is mutually exclusive of the maintenance intermediate point (MIP) and maintenance
endpoint (MEP) configuration commands. A port must be enabled before any MEPs or MIPs can be
configured. Similarly, maintenance points must be unconfigured before a port configured with MIPs or
MEPs can be disabled.
When CFM processing is disabled on a port, all CFM frames that arrive at that port are dropped and are
not processed by the CPU.
CFM is enabled by default on a port and must be disabled explicitly. When CFM is disabled on a port,
hardware resources such as port-ASIC match registers are released for that port.
Examples The following example shows how to configure an Ethernet interface for CFM processing:
Router(config-if)# ethernet cfm interface
Router(config-if)#
