Chapter 1 Overview

Identifying Interface Addresses

This section describes how to identify interface addresses for the 6T3 line card in the Cisco 7304 router.

Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on the 6T3 line card installed in a router maintain the same address regardless of whether other

line cards are installed or removed. However, when you move a line card to a different slot, the first

number in the interface address changes to reflect the new slot number.

Table 1-5 explains how to identify interface addresses.

Cisco 7304 Router Interface Addresses

This section describes how to identify the interface addresses used for the 6T3 line card in the

Cisco 7304 router. The interface address is composed of a two-part number in the format

slot-number/interface-port-number. See Table 1-5 for the interface address format.

In the Cisco 7304 router, slots are numbered from the lower left to the upper right, beginning with slot 0

and continuing through slot 5. (Slot 0 and slot 1 are reserved for the NSE.)

The interface address of the interfaces on a 6-port 6T3 line card in slot 2 are 2/0 through 2/5 (slot 2 and

interfaces 0 through 5). If the 6T3 line card was in slot 4, these same interfaces would be numbered 4/0

through 4/5 (slot 4 and interfaces 0 through 5).
