2.5 Configuring an Eth-Trunk Sub-interface

This section describes how to configure an Eth-Trunk sub-interface.

2.5.1 Establishing the Configuration Task

Applicable Environment
When two S7700s communicate with each other through a Layer 2 Eth-Trunk interface, MPLS
TE cannot be enabled on the main interface. In this case, to use the MPLS TE feature, you can
create a sub-interface on the Layer 2 Eth-Trunk interface and enable MPLS TE on the sub-
interface. In this manner, data of Layer 2 and Layer 3 services can be transmitted on the same
physical link.
Pre-configuration Tasks
Before configuring an Eth-Trunk sub-interface, complete the following tasks:

Data Preparation
To configure an Eth-Trunk sub-interface, you need the following data.
Issue 01 (2011-07-15)
Run the display trunkmembership eth-trunk trunk-id command to display the member
interfaces of the Eth-Trunk.
Run the display eth-trunk [ trunk-id [interface interface-type interface-number ] ]
command to display information about the Eth-Trunk and member interfaces.
