DETAILED STEPS
Command Purpose
Step 1
enable
Example:
Router> enable
Enables the privileged EXEC mode.
Enter your password when prompted.
Step 2
configure terminal
Example:
Router# configure terminal
Enters the global configuration mode.
Step 3
ethernet cfm domain domain-name level
level-id [direction outward]
Example:
Router(config)# ethernet cfm domain
Customer level 7 direction outward
Defines an outward CFM maintenance domain at a
particular maintenance level and enters Ethernet CFM
configuration mode.
Step 4
mep archive-hold-time minutes
Example:
Router(config-ecfm)# mep
archive-hold-time 60
Sets the amount of time that data from a missing MEP is
kept in the continuity check database or that entries are
held in the error database before they are purged.
Step 5
exit
Example:
Router(config-ecfm)# exit
Returns the device to global configuration mode.
