New Features in Cisco IOS Release 12.4(16)MR Chapter 1 Overview of the Cisco 3825 Mobile Wireless Edge Router interface ATM0/IMA0 no ip address atm bandwidth dynamic atm umts-iub no atm ilmi-keepalive pvc 2/1 encapsulation aal0 ! pvc 2/2 encapsulation aal0 ! umts-iub local 20.20.20.21 6666 umts-iub remote 20.20.20.20 6666 Note The above sample configuration has one IMA shorthaul with two member links (atm0/0/0 and atm 0/0/1). The output for the show umts-iub peering command has also changed and will look like the following: Router#show umts peer UMTS-Iub(ATM0/IMA0 - ATM0/IMA0): Peering Information UMTS-Iub(ATM0/IMA0 - ATM0/IMA0): Local (20.20.20.21:6666) States: UMTS-Iub(ATM0/IMA0 - ATM0/IMA0): Connect State: OPEN UMTS-Iub(ATM0/IMA0 - ATM0/IMA0): Redundancy State: ACTIVE UMTS-Iub(ATM0/IMA0 - ATM0/IMA0): Version: 4 UMTS-Iub(ATM0/IMA0 - ATM0/IMA0): Alarm State: UMTS-Iub(ATM0/0/0 - ATM0/0/0): RX(NO ALARM) TX(NO ALARM) UMTS-Iub(ATM0/0/1 - ATM0/0/1): RX(NO ALARM) TX(NO ALARM) UMTS-Iub(ATM0/IMA0 - ATM0/IMA0): Remote (20.20.20.20:6666) States: UMTS-Iub(ATM0/IMA0 - ATM0/IMA0): Version: 4 UMTS-Iub(ATM0/IMA0 - ATM0/IMA0): Alarm State: UMTS-Iub(ATM0/0/0 - ATM0/0/0): RX(NO ALARM) TX(NO ALARM) UMTS-Iub(ATM0/0/1 - ATM0/0/1): RX(NO ALARM) TX(NO ALARM) Note In the previous output, the local shorthaul/interface name appears before the dash (-), and the remote shorthaul/interface name appears after the dash (-). Permanent Virtual Circuit (PVC) Routing PVC Routing allows you to offload PVC traffic from a physical ATM shorthaul to an alternate backhaul. For each alternate backhaul, you will need to create a logical shorthaul by creating an ATM sub-interface. Traffic from the PVCs configured under this logical shorthaul will go through the corresponding alternate backhaul. Three new commands are added using the Sub-interface Configuration mode for this new feature: atm umts, umts local, and umts remote (see the "Configuring PVC Routing (HSDPA Offload)" section on page 4-41 and Appendix A, "Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference"). A sample configuration is written as follows: interface ATM0/IMA0 no ip address atm umts-iub no atm ilmi-keepalive pvc 2/1 encapsulation aal0 ! pvc 2/2 1-30 Cisco 3825 Mobile Wireless Edge Router Software Configuration Guide OL-15667-03
