Chapter 10 Configuring Ethernet OAM

Configuring ETH-AIS

Complete the following steps to configure ETH- AIS on the router:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	ethernet cfm ais link-status global	Configure AIS-specific SMEP commands by entering
		config-ais-link-cfm mode.
Step 3
	level level-id	Configure the maintenance level for sending AIS frames
		transmitted by the SMEP. The range is 0 to 7.
	or	or
	disable	Disable generation of ETH-AIS frames.
Step 4
	period value	Configure the SMEP AIS transmission period interval.
		Allowable values are 1 second or 60 seconds.
Step 5
	exit	Return to global configuration mode.
Step 6
	ethernet cfm domain domain-namelevel level-id	Define a CFM domain, set the domain level, and enter
		ethernet-cfm configuration mode for the domain. The
		maintenance level number range is 0 to 7.
Step 7
	service { short-ma-name number MA-number	Configure the maintenance association and set a
	vlan-idprimary-vlan-id vpn-idvpn-id } {vlan	universally unique ID for a customer service instance (CSI)
	vlan-id port evc evc-name }	or the maintenance association number value, primary
		VLAN ID and VPN ID within a maintenance domain in
		Ethernet connectivity fault management (CFM)
		configuration mode.
Step 8
	ais level level-id	(Optional) Configure the maintenance level for sending
		AIS frames transmitted by the MEP. The range is 0 to 7.
Step 9
	ais period value	(Optional) Configure the MEP AIS transmission period
		interval. Allowable values are 1 second or 60 seconds.
Step 10
	ais expiry-threshold value	(Optional) Set the expiring threshold for the MA as an
		integer. The range is 2 to 255. The default is 3.5.
Step 11
	no ais suppress-alarms	(Optional) Override the suppression of redundant alarms
		when the MEP goes into an AIS defect condition after
		receiving an AIS message.
Step 12
	exit	Return to ethernet-cfm configuration mode.
Step 13
	exit	Return to global configuration mode.
Step 14
	interface interface-id	Specify an interface ID, and enter interface configuration
		mode.
Step 15
	[no] ethernet cfm ais link-status	Enable or disable sending AIS frames from the SMEP on
		the interface.
Step 16
	ethernet cfm ais link-status period value	Configure the ETH-AIS transmission period generated by
		the SMEP on the interface. Allowable values are 1 second
		or 60 seconds.
Step 17
	ethernet cfm ais link-status level level-id	Configure the maintenance level for sending AIS frames
		transmitted by the SMEP on the interface. The range is 0 to
		7.
