DETAILED STEPS
PurposeCommand or Action
Enables privileged EXEC mode.enable
Step 1
Example:
Router> enable
•
Enter your password if prompted.
Enters global configuration mode.configure terminal
Example:
Router# configure terminal
Step 2
Specifies the Gigabit Ethernet interface to configure,
where:
interface gigabitethernet slot/subslot/port
Example:
Router(config)# interface Gi2/0/2
Step 3
slot/subslot/port—Specifies the location of the
interface.
Creates a service instance (an instance of an EVC)
on an interface and sets the device into the
config-if-srv submode.
service instance id Ethernet [service-name]
Example:
Router(config-if)# service instance 100 ethernet
Step 4
Configures the encapsulation. Defines the matching
criteria that maps the ingress dot1q, QinQ, or
encapsulation dot1q {any | vlan-id[vlan-id[-vlan-id]]}
second-dot1q {any | vlan-id[vlan-id[-vlan-id]]}
Step 5
untagged frames on an interface for the appropriate
service instance.
