Cisco Systems A9014CFD manual Verifying CFM with EVC Default Encapsulation, 10-25

Chapter 10 Configuring Ethernet OAM

	Command or Action	Purpose
Step 4
	service instance instance-idethernet evc-name	Creates a service instance on an interface and defines the
		matching criteria.
	Example:	• instance-id—Integer that uniquely identifies a service
	Router(config-if)# service instance 1 ethernet	instance on an interface.
	evc100	• evc-name—String that associates an EVC to the service
		instance. Maximum byte size is 100.
Step 5
	encapsulation default	Configures the default service instance.
	Example:
	Router(config-if-srv)# encapsulation default
Step 6
	bridge-domain bridge-id	Binds the service instance to a bridge domain instance using
		an identifier.
	Example:
	Router(config-if-srv)# bridge-domain 99
Step 7
	cfm encapsulation {dot1ad vlan-iddot1q	Configures connectivity fault management (CFM) Ethernet
	vlan-id} [dot1q vlan-id second-dot1qvlan-id]	frame encapsulation.
	Example:	• dot1ad—Indicates the 802.1ad provider bridges
		encapsulation type.
	Router(config-if-srv)# cfm encapsulation dot1q	• dot1q—Supports the IEEE 802.1q standard for
	75
		encapsulation of traffic and specifies the outer dot1q
		encapsulation tag.
		• second-dot1q—Specifies the inner dot1q
		encapsulation tag. Valid option only when you first
		select the outer dot1q encapsulation tag. When the
		dot1ad encapsulation type is selected first, dot1q is a
		valid option.
		• vlan-id—Integer from 1 to 4094 that specifies the
		VLAN on which to send CFM frames.
Step 8
	cfm mep domain domain-idmpid mpid-value	Configures a maintenance endpoint (MEP) for a domain.
		• domain-name—String from 1 to 154 characters that
	Example:	identifies the domain name.
	Router(config-if-srv)# cfm mep domain md2 mpid	• mpid—Indicates the maintenance point ID (MPID).
	111
		• mpid-value—Integer from 1 to 8191 that identifies the
		MPID.
