To enable connectivity fault management (CFM) processing on an interface, use the ethernet cfm
enable command in interface configuration mode. To disable CFM processing on an interface, use the
no form of this command.
Note This command was replaced by the ethernet cfm global command in Release 15.0(1)MR.
ethernet cfm enable
no ethernet cfm enable
Syntax Description This command has no arguments or keywords.
Command Default Ethernet CFM is enabled.
Command Modes Interface configuration (config-if)
Command History
Usage Guidelines Ethernet CFM is enabled by default on an interface and must be disabled explicitly. When CFM is
disabled on an interface, hardware resources (for example, port-ASIC match-registers) are released for
that interface.
This command is mutually exclusive of maintenance intermediate point (MIP) and maintenance end
point (MEP) configuration commands. The interface must be enabled before any MEPs or MIPs can be
configured. Similarly, disabling a port that has MIPs or MEPs configured is not allowed. The user must
first unconfigure the maintenance points.
When CFM processing is disabled on an interface, all CFM frames that arrive at that interface are
forwarded as normal data traffic, and are not processed by the CPU.
Examples The following example shows how to disable and then enable CFM processing on an interface:
Router(config-if)# no ethernet cfm enable
Router(config-if)# ethernet cfm enable
