Command Reference Guide
mep-validation
Use the mep-validation command to specify whether or not maintenance endpoints (MEPs) use a
comparison between their continuity check message (CCM) database (received CCMs) and their list of
configured remote MEPs (that should be sending CCMs) to generate an alarm when a mismatch is
discovered. The no form of this command disables MEP validation. Variations of this command include:
mep-validation
mep-validation start-delay <delay>
Syntax Description
start-delay <delay>
Default Values
By default, MEP validation is enabled with a delay of 30 seconds.
Command History
Release 17.4
Functional Notes
The MEP validation is used to compare an MEP's list of received CCMs with a list of MEPs that should be
sending CCMs. When MEP validation is enabled, an alarm is sent when a mismatch is discovered. By
default, each MEP validates their MEP list, and all CCMs received must correspond to preconfigured
remote MEPs in the maintenance association (MA).
Disabling validation (using the no form of the command), or changing the start delay, can be useful when
creating a domain association or when troubleshooting. Disabling validation in these circumstances
prevents unnecessary alarms and warnings. For example, if you wish to allow the unit to dynamically learn
its remote MEPs rather than manually entering them, disabling validation allows you to do that without
generating unnecessary alarms.

Usage Examples
The following example disables MEP validation:
(config-ecfm-domain)#association association1
(config-ecfm-assoc)#no mep-validation
(config-ecfm-assoc)#
60000CRG0-35E
Optional. Specifies a delay (in seconds) that the MEP will wait before
enforcing MEP validation. Delay range is 1 to 65535 seconds.
