Command Mode
Global Configuration
Command Usage
◆ For this trap type to function, cross-checking must be enabled on the required
maintenance associations using the ethernet cfm mep crosscheck command.
◆ A mep-missing trap is sent if cross-checking is enabled (with the ethernet cfm
mep crosscheck command), and no CCM is received for a remote MEP
configured in the static list (with the mep crosscheck mpid command).
◆ A mep-unknown trap is sent if cross-checking is enabled, and a CCM is received
from a remote MEP that is not configured in the static list.
◆ A ma-up trap is sent if cross-checking is enabled, and a CCM is received from all
remote MEPs configured in the static list for this maintenance association.
