Configuring AIS Parameters

To set the parameters for AIS, perform this task:
Command
Step 1
Switch# configure terminal
Step 2
Switch (config)# ethernet cfm ais domain name
vlan range
Step 3
Switch(config-ais-mep-cfm)# disable
Step 4
Switch(config-ais-mep-cfm)# period period
Step 5
Switch(config-ais-mep-cfm)# level level
Step 6
Switch(config-ais-mep-cfm)# expiry-threshold
threshold
Step 7
Switch(config-ais-mep-cfm)# express alarm
Step 8
Switch(config-ais-mep-cfm)# exit
Step 9
Switch(config)# [no] ethernet cfm ais
link-status global
Step 10
Switch(config-if)# [no] ethernet cfm ais
link-status period period
Step 11
Switch(config-if)# [no] ethernet cfm ais
link-status level level
Step 12
end
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
Step 14
Switch# show running-config
Step 15
Switch# copy running-config startup-config
Use the no versions of the commands to remove the configuration or return to the default configurations.
OL_28731-01
Purpose
Enters global configuration mode.
Enters config-ais-mep-cfm submode to configure
parameters for all local Meps belonging to that per
Maintenance Association (MA).
name refers to the domain name.
range represents VLAN IDs 100, 200-300, 400, 500, or
1-4095
For the domain name vlan range command only
configurations that are VLAN disjoint or congruent are
accepted.
Disables AIS transmission.
Sets the AIS transmission period.
Establishes a maintenance level to send AIS frames for
MEPs belonging to MA.
Valid levels are 0 to 7.
Sets the AIS expiry threshold.
By default, expiry threshold is 3.5. With this CLI we can
change the expiry threshold parameter for MA.
Configures alarm suppression when an AIS message
causes the MEP enters an AIS defect condition.
Returns to global configuration.
Enters config-ais-link-cfm submode, enabling you to
configure parameters required to follow when link status
goes down.
Configures ETH-AIS transmission period generated by the
link-status on the interface.
Configures maintenance level to send AIS frames
transmitted by the link-status on the interface.
Returns to privileged EXEC mode.
Verifies the configuration.
Verifies your entries.
(Optional) Saves your entries in the configuration file.
