Clearing MEP from the AIS Defect Condition
To clear the MEP, enter one of the following commands:
Switch# clear ethernet cfm ais domain domain name mpid local mpid vlan vlan#
Switch# clear ethernet cfm ais domain domain name mpid local mpid evc evc_name
Clearing SMEP from the AIS Defect Condition
To clear the CSMP, enter one of the following commands:
Switch# clear ethernet cfm ais link-status interface interface_name
Switch# clear ethernet cfm error
Note This operation also clears all error conditions including AIS.
Displaying Y.1731 Information
To display Y.1731 information, you can use the following commands (Table 76-1).
Step 6
Switch(config-ais-mep-cfm)# expiry-threshold
threshold

change the expiry threshold parameter for MA.
Step 7
Switch(config-ais-mep-cfm)# express alarm
Configures alarm suppression when an AIS message
causes the MEP enters an AIS defect condition.
Step 8
Switch(config-ais-mep-cfm)# exit
Returns to global configuration.
Step 9
Switch(config)# [no] ethernet cfm ais
link-status global
Enters config-ais-link-cfm submode, enabling you to
configure parameters required to follow when link status
goes down.
Step 10
Switch(config-if)# [no] ethernet cfm ais
link-status period period
Configures ETH-AIS transmission period generated by the
link-status on the interface.
Step 11
Switch(config-if)# [no] ethernet cfm ais
link-status level level
Configures maintenance level to send AIS frames
transmitted by the link-status on the interface.
Step 12
end
Returns to privileged EXEC mode.
Step 13
Switch# show ethernet cfm smep interface name
Switch# show ethernet cfm maintenance-points
local detail
Switch# show ethernet cfm maintenance-points
remote detail
Switch# show ethernet cfm error
Verifies the configuration.
Step 14
Switch# show running-config
Verifies your entries.
