Purpose
Command or Action
Defines a CFM maintenance domain at a particular
maintenance level and enters Ethernet CFM configuration
mode.
ethernet cfm domain domain-name level level-id
Example:
Device(config)# ethernet cfm domain Customer level
7
Step 3
Configures a maintenance association within a
maintenance domain and enters Ethernet connectivity
fault management (CFM) service configuration mode.
service short-ma-name evc evc-name vlan vlanid direction
down
Example:
Device(config-ecfm)# service s41 evc 41 vlan 41
direction down
Step 4
Configures the transmission of continuity check
messages (CCMs).
continuity-check
Example:
Device(config-ecfm-srv)# continuity-check
Step 5
Configures the per-service parameters and sets the
interval at which CCMs are transmitted.
continuity-check
[
interval cc-interval
]
Example:
Device(config-ecfm-srv)# continuity-check interval
10s
Step 6
Returns to Ethernet connectivity fault management
configuration mode.
exit
Example:
Device(config-ecfm-srv)# exit
Step 7
Enables CFM processing globally on the device.
ethernet cfm global
Example:
Device(config)# ethernet cfm global
Step 8
Enables caching of CFM data learned through traceroute
messages.
ethernet cfm traceroute cache
Example:
Device(config)# ethernet cfm traceroute cache
Step 9
Sets the maximum size for the CFM traceroute cache
table.
ethernet cfm traceroute cache size entries
Example:
Device(config)# ethernet cfm traceroute cache
size 200
