Command Usage
◆ 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 through CCMs.
◆ 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.
