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 1-11 .
The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See
Table 1-2 . For example, if a single-port PA-E3 is
installed in slot 1of a Cisco uBR7223 series router, the interface address would be 1/0. If a dual-port
PA-2E3 is installed in slot 1of a Cisco uBR7223 series router, the interface addresses would be 1/0 and
1/1. If the single-port PA-E3 were installed in slot 2 of a Cisco uBR7246 or Cisco uBR7246VXR router,
the interface address would be 2/0. If the dual-port PA-2E3 were installed in slot 2 of a Cisco uBR7246
or Cisco uBR7246VXR router, the interface addresses would be 2/0 and 2/1.
Cisco 7201 Router Interface Addresses
In the Cisco 7201 router, only one slot accepts port adapters and it is numbered as slot 1. 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 1-2 . For example, if a single-port PA-E3 is
installed in a Cisco 7201 router, the interface address would be 1/0. If a dual-port PA-2E3 is installed in
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 as slot 1. 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 1-2 . For example, if a single-port PA-E3 is
installed in a Cisco 7301 router, the interface address would be 1/0. If a dual-port PA-2E3 is installed in
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 1-15 .
The interface address is composed of a two-part number in the format
module-slot-number/interface-port-number. See
Table 1-2 . For example, if a single-port PA-E3 is
installed in the Cisco 7304 PCI port adapter carrier card in Cisco 7304 router module slot 3, the interface
address would be 3/0. If a dual-port PA-2E3 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 3/1.
