Note For the Cisco 7206VXR and Cisco 7206 router shelves, physical port addresses are composed of a three-part number in the format shelf number/port adapter slot number/interface port number, where the shelf number is a number assigned to the router shelf during the initial configuration of the Cisco AS5800 Universal Access Server. A Cisco AS5800 Universal Access Server can consist of several shelves; therefore, each shelf is assigned a shelf number.

The Cisco 7206VXR and the Cisco 7206 can be used as router shelves in a Cisco AS5800 Universal Access Server. For information about the Cisco 7206VXR and the Cisco 7206 as router shelves, see the Cisco 7200 Series Port Adapter Hardware Configuration Guidelines .

You can identify interface ports by physically checking the slot/interface port location on the front of the router or by using show commands to display information about a specific interface or all interfaces in the router.

Interface ports maintain the same address regardless of whether other port adapters are installed or removed from the slot. However, when you move a port adapter to a different slot, the port adapter slot number in the address changes to reflect the new slot number.

In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right, beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4 for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. Port adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present. Figure 8-1 shows the interface port of a PA-FE-TX installed in slot 4 of a Cisco 7206.

Note: The MII and RJ-45 interface ports on the port adapter are both numbered as interface port 0. Only one interface can be used on each port adapter at a time.

Note The I/O controller is available with or without a Fast Ethernet port. You can install both I/O controller types in all Cisco 7200 series routers; however, when you install an I/O controller with a Fast Ethernet port in a Cisco 7202, the system software automatically disables the port.
