Step 26 Exit the sub-interface configuration mode.

Router(config-subif)# exit

Note For more information about PVC Routing, see the “Permanent Virtual Circuit (PVC) Routing” section on page 1-30. Example output from the show umts peer command as well as specific behavior changes are described.

Configuring UMTS QoS

Three new commands are added using the Interface Configuration mode for this new feature: umts-iub set dscp, umts-iub set peering dscp, and gsm-abis set dscp and one new ATM-VC Interface Configuration command: umts-iub set dscp (see Appendix A, “Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference” for detailed command information). These new commands allow you to perform the following:

•UMTS Shorthaul Interface

–Set the default description value to tag the backhaul packet including peering and data generated from the shorthaul in a UMTS Iub configuration.

–Set the description value in the UMTS Iub configuration such that it overwrites the default value defined previously. It is also used to tag the peering backhaul packet.

•PVC of a UMTS Shorthaul Interface

–Set the description value in the UMTS Iub configuration such that it overwrites the default value defined previously. It is also used to tag the backhaul packet generated from traffic from the PVC.

•GSM Shorthaul Interface

–Set the description value in such a way as to tag all the backhaul packets generated from the shorthaul in the GSM Abis interface.

In the following procedures, PVC 2/1 of ATM0/0/0 and ATM0/0/1 will go to the priority queue and PVC 2/2 of ATM0/0/0 and ATM0/0/1 will be considered the best effort traffic and will go to the Weighted Fair Queue.

Note Defining the dscp value under the PVC affects the way the ATM cells are bundled together as a backhaul. The more dscp values that are defined, the more limitations on how the ATM cells can be bundled. This, as a result, could affect backhaul efficiency. We recommend that you define at most two different dscp values for each shorthaul. One for llq traffic, and the other for best effort traffic.
