Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line Configuration Sequence Configuring PVC Routing (HSDPA Offload) A new feature, PVC Routing has been implemented in Cisco IOS Release 12.4(4)MR. With this feature, you can now off load 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 Appendix A, "Cisco 3825 Mobile Wireless Edge Router RAN-O Command Reference" for detailed command information). To configure a Cisco 3825 router for PVC Routing, follow these steps while in the global configuration mode: Step 1 Step 2 Step 3 Step 4 Step 5 Step 6 First, add the Gigabit Ethernet interfaces by specifying the port adapter type and the location of the interface to be configured. Router(config)# interface gigabitethernet slot/port The slot represents the main fixed slot and is always 0 and the port is the number of the port (0 or 1). For example, the following command specifies the slot number as 0 and the port number as 0: Router(config)# interface gigabitethernet 0/0 Assign an IP address and subnet mask to the interface. Router(config-if)# ip address ip_address subnet_mask For example, the following command specifies the IP address 192.168.1.1 and subnet mask 255.255.255.0: Router(config-if)# interface ip address 192.168.1.1 255.255.255.0 Specify the duplex operation. Router(config-if)# duplex [auto | half | full] For example, the following command specifies the duplex operation as auto: Router(config-if)# duplex auto Specify the speed. Router(config-if)# speed [auto | 1000 | 100 | 10] For example, the following command specifies the speed as auto: Router(config-if)# speed auto Exit the interface configuration mode. Router(config-if)# exit Enter interface configuration mode and specify the location of the interface. Router(config)# interface atmslot/subslot/port Where: • slot-Specifies the slot number of the VWIC/HWIC previously assigned to the AIM for ATM (Step 2 of the "Configuring UMTS Links" procedure on page 4-24). • subslot-Specifies the subslot number of the VWIC/HWIC previously assigned to the AIM for ATM card (Step 2 of the "Configuring UMTS Links" procedure on page 4-24).
