defects within the configured time period, and fault alarms are enabled, a
corresponding trap will be sent. No further fault alarms are sent until the
fault notification generator has been reset by the passage of a configured
time period without detecting any further faults. Upon receiving a fault
alarm, you should inspect the related SNMP objects for the reporting MEP,
diagnose the fault, correct it, and re-examine the MEP’s SNMP objects to
see whether the fault notification generator has been reset.
Configuration Guidelines
1.
Configure the maintenance domains with the MD List (see Configuring
CFM Maintenance Domains).
2.
Configure the maintenance associations with MA List (see Configuring
CFM Maintenance Associations).
3.
Configure the local maintenance end points (MEPs) which will serve as
the domain service access points for the specified maintenance
association using the MEP List (see Configuring CFM Maintenance
4.
Enter a static list of MEPs assigned to other devices within the same
maintenance association using the Remote MEP List (see Configuring
Remote Maintenance End Points). This allows CFM to automatically
verify the functionality of these remote end points by cross-checking
the static list configured on this device against information learned
through continuity check messages.
5.
Enable CFM globally on the switch using the Configure Global screen
(see Configuring Global Settings for CFM).
6.
Enable CFM on the local MEPs using the Configure Interface screen (see
Configuring Interfaces for CFM).
7.
Enable continuity check and cross-check operations, and configure AIS
parameters using the Configure MA – Configure Details screen (see
Configuring CFM Maintenance Associations).
Other configuration changes may be required for your particular
environment, such as adjusting the interval at which continuity check
messages are sent (see Configuring CFM Maintenance Associations), or
setting the start-up delay for the cross-check operation (see Configuring
Global Settings for CFM). You can also enable SNMP traps for events
discovered by continuity check messages or cross-check messages (see
Configuring Global Settings for CFM).

CFM
Use the Administration > CFM (Configure Global) page to configure global
settings for CFM, such as enabling the CFM process on the switch, setting
the start-up delay for cross-check operations, configuring parameters for
the link trace cache, and enabling traps for events discovered by continuity
check messages or cross-check messages.
