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").
Configuring Global
Settings for 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.
Parameters
These parameters are displayed:
Global Configuration
CFM Status
– Enables CFM processing globally on the switch.
(Default: Enabled)
To avoid generating an excessive number of traps, the complete CFM
maintenance structure and process parameters should be configured prior to
enabling CFM processing globally on the switch. Specifically, the maintenance
domains, maintenance associations, and maintenance end-points (MEPs)
should be configured on each participating bridge using the Configure MD
page (see "Configuring CFM Maintenance Domains"), Configure MA page (see
"Configuring CFM Maintenance Associations"), and the Configure MEP page
(see "Configuring Maintenance End Points").
When CFM is enabled, hardware resources are allocated for CFM processing.
