Overview
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
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
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
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.
Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and the 13-slot Cisco 7513 and
Note
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
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
processor slot 3 and install it in interface processor slot 2, the interface addresses become 2/1/0 through
2/1/7.
