Chapter 10 Configuring Ethernet OAM

Understanding E-LMI

Enabling E-LMI

You can enable E-LMI globally or on an interface and you can configure the router as a PE device. Beginning in privileged EXEC mode, follow these steps to enable for E-LMI on the router or on an interface. Note that the order of the global and interface commands determines the configuration. The command that is entered last has precedence.

	Command	Purpose
Step 1
	configure terminal	Enter global configuration mode.
Step 2
	ethernet lmi global	Globally enable E-LMI on all interfaces. By default, the
		router is a PE device.
Step 3
	interface interface-id	Define an interface to configure as an E-LMI interface, and
		enter interface configuration mode.
Step 4
	ethernet lmi interface	Configure Ethernet LMI on the interface. If E-LMI is
		enabled globally, it is enabled on all interfaces unless you
		disable it on specific interfaces. If E-LMI is disabled
		globally, you can use this command to enable it on
		specified interfaces.
Step 5
	ethernet lmi {n391 value n393 value t391 value	Configure E-LMI parameters for the UNI.
	t392 value}	The keywords have these meanings:
		• n391 value—Set the event counter on the customer
		equipment. The counter polls the status of the UNI and
		all Ethernet virtual connections (EVCs). The range is
		from 1 to 65000; the default is 360.
		• n393 value—Set the event counter for the metro
		Ethernet network. The range is from 1 to 10; the
		default is 4.
		• t391 value—Set the polling timer on the customer
		equipment. A polling timer sends status enquiries and
		when status messages are not received, records errors.
		The range is from 5 to 30 seconds; the default is 10
		seconds.
		• t392 value—Set the polling verification timer for the
		metro Ethernet network or the timer to verify received
		status inquiries. The range is from 5 to 30 seconds, or
		enter 0 to disable the timer. The default is 15 seconds.
		Note The t392 keyword is not supported when the router
		is in CE mode.
Step 6
	end	Return to privileged EXEC mode.
Step 7
	show ethernet lmi evc	Verify the configuration.
Step 8
	copy running-config startup-config	(Optional) Save your entries in the configuration file.

Use the no ethernet lmi global configuration command to globally disable E-LMI. Use the no form of the ethernet lmi interface configuration command with keywords to disable E-LMI on the interface or to return the timers to the default settings.
