CFM Commands

Basic Configuration Steps for CFM

1. Configure the maintenance domains with the

ethernet cfm domain

command.

2. Configure the maintenance associations with the

ma index name

command.

3. Configure the local maintenance end points (MEPs) which will serve as the domain service

access points for the specified maintenance association using the

ethernet cfm mep

command.

4. Enter a static list of MEPs assigned to other devices within the same maintenance association

using the

mep crosscheck mpid

command. 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 with the

ethernet cfm enable

command.

6. Enable CFM on the local MEPs with the

ethernet cfm port-enable

command.

7. Enable continuity check operations with the

ethernet cfm cc enable

command.

8. Enable cross-check operations with the

ethernet cfm mep crosscheck

command.

Other configuration changes may be required for your particular environment, such as adjusting
the interval at which continuity check messages are sent (see

“ethernet cfm cc ma interval”

on

page 537), or setting the start-up delay for the cross-check operation (see

“ethernet cfm mep

crosscheck start-delay”

on page 542). You can also enable SNMP traps for events discovered by

continuity check messages (see

“snmp-server enable traps ethernet cfm cc”

on page 539) or

cross-check messages (see

“snmp-server enable traps ethernet cfm crosscheck”

on page 543).

Loss Measure Operations

ethernet cfm loss-measure
dual-ended destination

Sets the destination MEP for periodically transmitted continuity check
messages, including request dual-ended frame loss measurements

GC

ethernet cfm loss-measure
enable

Enables periodic transmission of loss-measure messages

GC

ethernet cfm loss-measure
single-ended binding

Binds periodic loss-measure settings to a specified local MEP

GC

ethernet cfm loss-measure
single-ended destination

Sets the destination MEP for periodically transmitted loss-measure
messages

GC

ethernet cfm loss-measure
single-ended group

Sets attributes for periodically transmitted loss-measure messages,
including transmission cycle, duration, interval, and timeout

GC

ethernet cfm loss-measure
single-ended

Sends on-demand loss-measure information to a specified MEP,
stamped with the time of transmission

PE

show ethernet cfm
loss-measure single-ended

Displays near-end and far-end frame loss for on-demand single-ended
loss-measure test
