Identifying Chassis Slot, Port Adapter Slot, and HSSI Interface Port Numbers

The following sections describes how to identify the chassis slot, port adapter slot, and HSSI port

numbers for the Cisco 7200 series, Cisco uBR7200 series routers, the VIP2, and the

Catalyst RSM/VIP2.

Ina Cisco 7200 series (see Figure 7-2) or Cisco uBR7200 series router (see Figure 7-3) physical port

addresses specify the actual physical location of each interface port on the router. This address is

composed of a two-part number in the format port adapter slotnumber/interface port number, as

follows:

•The ﬁrst number identiﬁes the port adapter slot in which the HSSI port adapter is installed.

•The second number identiﬁes the interface ports on the HSSI port adapter; these are always

numbered as interface 0 and 1 for PA-2H.

Note For the Cisco 7206 and Cisco7206VXR router shelves, physical port addresses are

composedof 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 Cisco 7206 or Cisco 7206VXR router

shelfduring 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.

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.

For the Cisco 7206 (including a Cisco7206 and Cisco 7206VXR as router shelves in a

Cisco AS5800 Universal Access Server), the port adapter slot numbers start with 1 and continue

through 6. Forthe Cisco uBR7200 series routers, the port adapter slots are numbered 1 and 2 for the

Cisco uBR7246 and slot1 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 are always0. For

example, the HSSI port on an HSSI port adapter in port adapter slot 2 would have the address 2/0.

If the HSSI port adapter was in port adapter slot 1, this same interface port would be 1/0.

Note Forthe Cisco 7206 and Cisco 7206VXR router shelves, the HSSI port adapter in port adapter

slot 2 would have the addressx/2/0, where x is the number assigned to the router shelf during the

initial conﬁguration of the Cisco AS5800 Universal Access Server.
