Chapter 9 Configuring EtherChannels
EVC On Port-Channel
Configuring EVC on Port-Channel
To configure the EVC on port-channel, complete these steps in the interface configuration mode:
Verifying the Configuration
Use the following commands to verify the configuration:
Command Purpose
Step 1
interface port-channel
number
Example:
Router(config)# interface port-channel
11
Creates the port-channel interface.
Step 2
[no] service instance
id
Ethernet
[service-name}
Example:
Router(config-if)# service instance 101
ethernet
Creates a service instance (an instantiation of an EVC)
on an interface and sets the device into the config-if-srv
submode.
Step 3
encapsulation {untagged|dot1q
vlan-id
[second-dot1q
vlan-id
]}
Example:
Router(config-if-srv)# encapsulation
dot1q 13
Defines the matching criteria to be used in order to map
ingress dot1q frames on an interface to the appropriate
service instance.
Step 4
rewrite ingress tag pop 1 symmetric
Example:
Router(config-if-srv)# rewrite ingress
tag pop 1 symmetric
Specifies the tag manipulation that is to be performed
on the frame ingress to the service instance.
Step 5
[no] bridge-domain
bridge-id
Example:
Router(config-if-srv)# bridge-domain 12
The bridge-domain command binds the service instance
to a bridge domain instance where bridge-id is the
identifier for the bridge domain instance.
Command Purpose
Router# show ethernet service evc [id evc-id | interface
interface-id] [detail]
Displays information pertaining to a specific EVC if an EVC
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
port-channel number [summary]
Displays the summary of all the configured EVCs within the
interface.
