Chapter 1 Overview
Identifying Interface Addresses
Cisco uBR7200 Series Routers Interface Addresses
In the Cisco uBR7223 router, only one slot accepts port adapters and it is numbered slot 1.
In the Cisco uBR7246 router and Cisco uBR7246VXR router, port adapters can be installed in two port
adapter slots (slot1 and slot 2). Slot 0 is always reserved for the I/O controller—if present. See
Figure 1-13.
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 uBR7223 series router, the interface addresses would be 1/0 and 1/1 (slot 1
and ports 0 and 1). If the dual-port port adapter were installed in slot 2 of a Cisco uBR7246 or
Cisco uBR7248VXR router, the interface addresses would be 2/0 and 2/1 (slot 2 and ports 0 and 1).
Cisco 7201 Router Interface Addresses
In the Cisco 7201 router, only one slot accepts port adapters and it is numbered slot 1. See Figure 1-14.
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 7201 router, the interface addresses would be 1/0 and 1/1.
Cisco 7301 Router Interface Addresses
In the Cisco 7301 router, only one slot accepts port adapters and it is numbered slot 1. See Figure 1-15.
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 7301 router, the interface addresses would be 1/0 and 1/1.
Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses
In the Cisco 7304 router, port adapters are installed in a Cisco 7304 PCI port adapter carrier card, which
installs in Cisco 7304 router module slots 2 through 5. The port adapter slot number is the same as the
module slot number. See Figure 1-16.
The interface address is composed of a two-part number in the format
module-slot-number/interface-port-number. See Table 1-4. For example, if a dual-port PA-2FE is
installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface
addresses would be 3/0 and 3/2.
Cisco 7401ASR Router Interface Addresses
In the Cisco 7401ASR router, only one slot accepts port adapters and it is numbered slot 1. See
Figure 1-18.
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 7401ASR router, the interface addresses would be 1/0 and 1/1.
