Chapter 1 Overview

Identifying Interface Addresses

Table 1-4	Identifying Interface Addresses (continued)
Platform		Interface Address Format	Numbers	Syntax
Cisco 7201 router		Port-adapter-slot-number/interface-port-number	Port adapter slot—always 1	1/0
			Interface port—0 or 1
Cisco 7301 router		Port-adapter-slot-number/interface-port-number	Port adapter slot—always 1	1/0
			Interface port—0 or 1
Cisco 7304 PCI port adapter		Module-slot-number/interface-port-number	Module slot— slot 2 through	3/0
carrier card in Cisco 7304			5
router			Interface port—0 or 1
Cisco 7401ASR router		Port-adapter-slot-number/interface-port-number	Port adapter slot—always 1	1/0
			Interface port—0 or 1
VIP in Cisco 7500 series		Interface-processor-slot-number/port-adapter-slot-	Interface processor slot—0	3/1/0
routers		number/interface-port-number	through 12 (depends on the
			number of slots in the
			router)
			Port adapter slot— 0 or 1
			Interface port—0 or 1

Note In Cisco 7200 series routers, Cisco 7200 VXR routers, and Cisco uBR7200 series routers, port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller, if present.

Cisco 7120 Router and Cisco 7140 Router Interface Addresses

In the Cisco 7120 series router, port adapters are installed in port adapter slot 3. See Figure 1-10. In the Cisco 7140 series router, port adapters are installed in port adapter slot 4. See Figure 1-11.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number.See Table 1-4. For example, if a dual-port PA-2FE is installed on a Cisco 7120 router, the interface addresses would be 3/0 and 3/1. If a dual-port PA-2FE is installed on a Cisco 7140 router, the interface addresses would be 4/0 and 4/1.

Cisco 7200 Series Routers and Cisco 7200 VXR Routers Interface Addresses

In Cisco 7200 series routers and Cisco 7200 VXR routers, port adapter slots are numbered from the lower left to the upper right, beginning with slot 1 and continuing through 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 adapters can be installed in any available port adapter slot from 1 through 6 (depending on the number of slots in the router). (Slot 0 is reserved for the I/O controller.) See Figure 1-12.

The interface address is composed of a two-part number in the format port-adapter-slot-number/interface-port-number. See Table 1-4. For example, if a dual-port PA-2FE is installed in slot 1of a Cisco 7200 series router, the interface addresses would be 1/0 and 1/1 (slot 1 and ports 0 and 1). If the dual-port PA-2FE were installed in slot 4, the interface addresses would be 4/0 and 4/1 (slot 4 and ports 0 and 1)
