Identifying Interface Addresses

This section describes how to identify the interface addresses for the port adapter slots and ESCON channel port numbers. Interface 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 HP ESCON PA is installed.

•The second number identifies the interface port on the HP ESCON PA, which is always numbered as interface 0 for the HP ESCON PA.

Note Some IBM channel attach software features are configured on a virtual port. On the CIP cards installed in a Cisco 7500-series router, there are up to two physical ports, numbered 0 and 1, and a virtual port, numbered 2. However, on the HP ESCON PA installed in a Cisco 7200 series router, the single physical port and the virtual port are configured using the same port number identifier, number 0.

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 port adapter slot number.

Note The HP ESCON PA is considered a high-speed port adapter; there are specific configuration guidelines that must be observed. Refer to the publication Cisco 7200 Series Port Adapter Hardware Configuration Guidelines (Document Number 78-3471-xx), which shipped with your Cisco 7200 series chassis and is also available on the Cisco Connection Documentation, Enterprise Series CD-ROM.

The following subsections describe the interface address formats for the supported platforms:
