Chapter 1 Overview
Identifying Interface Addresses
Cisco 7301 Router Interface Addresses
This section describes how to identify the interface addresses used for the port adapter in Cisco 7301
router. The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See
Table 1-6 on page 1-22 for the interface address
format.
Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-232 in the Cisco 7304
PCI Port Adapter Carrier Card in Cisco 7304 routers. The interface address is made of a two-part number
in the format port-adapter-slot-number/interface-port-number.
The Cisco 7304 PCI Port Adapter Carrier Card installs into Cisco 7304 router module slots 2 through 5
(See
Figure 1-13 .) The port-adapter-slot-number is the Cisco 7304 router module slot number. For
example, the interface address of port 0 on a PA-8T-232, in which the Cisco 7304 PCI Port Adapter
Carrier Card is installed in Cisco 7304 router module slot 3, would be numbered 3/0.
Cisco 7401ASR Router Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-232 in the
Cisco 7401ASR router. In the Cisco 7401ASR router, slot 1 is the port adapter slot you use for the
PA-8T-232. The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See
Table 1-6 on page 1-22 for the interface address
format.
VIP Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-232 on a VIP in
Cisco 7000 series and Cisco 7500 series routers.
Note Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and the 13-slot Cisco 7513 and
Cisco 7576 are vertically oriented and those in the 5-slot Cisco 7010 and Cisco 7505 are horizontally
oriented, all Cisco 7000 series and Cisco 7500 series routers use the same method for slot and port
numbering.
See Table 1-6 on page 1-22 for the interface address format. The interface address is composed of a
three-part number in the format interface-processor-slot-number/port-adapter-slot-number/
interface-port-number.
If the VIP is inserted in interface processor slot 3, then the interface addresses of the PA-8T-232 are 3/1/0
through 3/1/7 (interface processor slot 3, port adapter slot 1, and interfaces 0 through 7). If the
port adapter was in port adapter slot 0 on the VIP, these same interface addresses would be numbered
3/0/0 through 3/0/7.
Note
If you remove the VIP with the PA-8T-232 (shown in Figure 1-16 on page 1-22 ) from interface
processor slot 3 and install it in interface processor slot 2, the interface addresses become 2/1/0 through
2/1/7.
