Cisco 7200 Series and Cisco uBR7200 Series Ports

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 first number in the address changes to reflect the new chassis 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 port adapter slots and interface ports of a Cisco 7206. The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter.

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.

For example, the serial port on a one-port PA-E3 in port adapter slot 3 has the address 3/0.

(See Figure 8-1.) If the PA-E3 is in port adapter slot 1, this same interface port is numbered 1/0. The serial ports on a two-port PA-2E3 in port adapter slot 3 have the addresses 3/0 and 3/1.

Note The PA-E3 is considered a high-bandwidth port adapter; you must observe specific configuration guidelines. Refer to the publication Cisco 7200 Series Port Adapter Hardware Configuration Guidelines , which shipped with your Cisco 7200 series chassis and is also available on the Cisco Connection Documentation, Enterprise Series CD-ROM.

PA-E3 port adapter (port number 3/0)

Figure 8-2 shows the interface ports of a PA-E3 in slot 2 of a Cisco uBR7200 series router. The port adapter slots are numbered slot 1 and slot 2 for the Cisco uBR7246 and slot 1 for the Cisco uBR7223 (slot 0 is always reserved for the Fast Ethernet port on the I/O controller if present). The individual interface port numbers always begin with 0. The number of additional ports depends on the number of ports on a port adapter. Port adapters can occupy any port adapter slot; there are no restrictions.

For example, the serial port on a one-port PA-E3 in port adapter slot 1 has the address 1/0.

(See Figure 8-2.) If the PA-E3 is in port adapter slot 2, this same interface port is numbered 2/0. The serial ports on a two-port PA-2E3 in port adapter slot 2 have the addresses 2/0 and 2/1.
