COMMAND USAGE
â—† This command sets the delay that a device waits for a remote MEP to
come up, and it starts cross-checking the list of statically configure
remote MEPs in the local maintenance domain against the MEPs learned

â—† The cross-check start delay should be configured to a value greater
than or equal to the continuity check message interval to avoid
generating unnecessary traps.
EXAMPLE
This example sets the maximum delay before starting the cross-check
process.
Console(config)#ethernet cfm mep crosscheck start-delay 60
Console(config)#

crosscheck
