Appendix B Cisco MWR 2941 Router Command Reference
ethernet cfm cc
Command History
Usage Guidelines The ethernet cfm cc command is used to set parameters for generating and receiving CCMs in one of
the following ways:
• Globally (per device)
• For a maintenance domain
• For a particular customer service instance (CSI)
• For a combination of maintenance domain and CSI
When the ethernet cfm cc command is issued, the system may perform optimizations by concatenating
possible ranges, and the configuration may not go through nonvolatile generation (NVGEN) as it was
originally entered.
If you configure the ethernet cfm cc command with the default values for interval and loss threshold,
these parameters are not displayed after NVGEN. If you configure the command with at least one
parameter not at the default value, all parameters are displayed.
An EVC is an association of two or more user network interfaces (UNIs).
Note This command is not supported in the Connectivity Fault Management 802.1ag Standard (CFM IEEE).
Examples The following example shows how to configure an Ethernet CFM level ID of 5 for all VLANs, with
messages transmitted every 30 seconds and a remote MEP declared down after two messages are missed.
Note that the interval and loss-threshold parameters are configured for the default values and do not
display after NVGEN.
Router(config)# ethernet cfm cc level 5 vlan any interval 30 loss-threshold 2
(NVGEN)ethernet cfm cc level 5 vlan any
The following example shows how to configure an Ethernet CFM level ID of 5 for all VLANs, with
messages transmitted every 1000 seconds and a remote MEP declared down after two messages (the
default value) are missed:
Router(config)# ethernet cfm cc level 5 vlan any interval 1000 loss-threshold 2
(NVGEN)ethernet cfm cc level 5 vlan any interval 1000
The following example shows how to configure an Ethernet CFM level ID of 5 for all VLANs, with
messages transmitted every 1000 seconds and a remote MEP declared down after 7 messages are missed
(neither value is a default value):
Router(config)# ethernet cfm cc level 5 vlan any interval 1000 loss-threshold 7
(NVGEN)ethernet cfm cc level 5 vlan any interval 1000 loss-threshold 7
