EVC On Port-Channel

Configuring EVC on Port-Channel

To configure the EVC on port-channel, complete these steps in the interface configuration mode:

	Command	Purpose
Step 1	interface port-channel number	Creates the port-channel interface.
	Example:
	Router(config)# interface port-channel
	11
Step 2	[no] service instance id Ethernet	Creates a service instance (an instantiation of an EVC)
	[service-name}	on an interface and sets the device into the config-if-srv
		submode.
	Example:
	Router(config-if)# service instance 101
	ethernet
Step 3	encapsulation {untaggeddot1q vlan-id	Defines the matching criteria to be used in order to map
	[second-dot1q vlan-id]}	ingress dot1q frames on an interface to the appropriate
		service instance.
	Example:
	Router(config-if-srv)# encapsulation
	dot1q 13
Step 4	rewrite ingress tag pop 1 symmetric	Specifies the tag manipulation that is to be performed
		on the frame ingress to the service instance.
	Example:
	Router(config-if-srv)# rewrite ingress
	tag pop 1 symmetric
Step 5	[no] bridge-domain bridge-id	The bridge-domain command binds the service instance
		to a bridge domain instance where bridge-idis the
	Example:	identifier for the bridge domain instance.
	Router(config-if-srv)# bridge-domain 12

Verifying the Configuration

Use the following commands to verify the configuration:

Command	Purpose
Router# show ethernet service evc [id evc-idinterface	Displays information pertaining to a specific EVC if an EVC
interface-id] [detail]	ID is specified, or pertaining to all EVCs on an interface if an
	interface is specified. The detailed option provides additional
	information on the EVC.
Router# show ethernet service instance interface	Displays the summary of all the configured EVCs within the
port-channel number [summary]	interface.
