Purpose
Enables privileged EXEC mode.
Enter your password if prompted.
•
Enters global configuration mode.
Enters interface configuration mode.
The example shows how to configure Gigabit
•
Ethernet interface 0/1 and enter interface
configuration mode.
Configures an Ethernet service instance on an interface
and enters Ethernet service configuration mode.
The example shows how to configure Ethernet
•
service instance 1.
Defines the encapsulation type.
The example shows how to define dot1q as the
•
encapsulation type.
(Optional) Specifies the encapsulation adjustment to be
performed on a frame ingressing a service instance.
•
The example shows how to specify translating a
single tag defined by the encapsulation command to
a single tag defined in the rewrite ingress tag
command with reciprocal adjustment to be done in
the egress direction.
