Chapter 10 Configuring Ethernet OAM

Enabling Ethernet OAM Remote Loopback

Enable Ethernet OAM remote loopback on an interface for the local OAM client to initiate OAM remote loopback operations. Changing this setting causes the local OAM client to exchange configuration information with its remote peer. Remote loopback is disabled by default.

Restrictions

•Internet Group Management Protocol (IGMP) packets are not looped back.

•If dynamic ARP inspection is enabled, ARP or reverse ARP packets are not looped or dropped. Complete the following steps to enable Ethernet OAM remote loopback on an interface:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface interface-id	Define an interface to configure as an EOM interface, and
		enter interface configuration mode.
Step 3
	ethernet oam remote-loopback {supported	Enable Ethernet remote loopback on the interface or set a
	timeout seconds}	loopback timeout period.
		• Enter supported to enable remote loopback.
		• Enter timeout seconds to set a remote loopback
		timeout period. The range is from 1 to 10 seconds.
Step 4
	end	Return to privileged EXEC mode.
Step 5
	ethernet oam remote-loopback {start stop}	Turn on or turn off Ethernet OAM remote loopback on an
	{interface interface-id}	interface.
Step 6
	show ethernet oam status [interface interface-id]	Verify the configuration.
Step 7
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

Use the no ethernet oam remote-loopback disable remote loopback support or remove

{supported timeout} interface configuration command to the timeout setting.

Configuring Ethernet OAM Link Monitoring

You can configure high and low thresholds for link-monitoring features. If no high threshold is configured, the default is none —no high threshold is set. If you do not set a low threshold, it defaults to a value lower than the high threshold.

Complete the following steps to configure Ethernet OAM link monitoring on an interface:

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	interface interface-id	Define an interface, and enter interface configuration
		mode.
