Identifying Interface Addresses
Cisco 7304 PCI Port Adapter Carrier Card Interface Addresses
This section describes how to identify the interface addresses used for the PA-T3+ and PA-2T3+ 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 1-10.) The port-adapter-slot-number is the Cisco 7304 router module slot number. For
example, the interface address of port 0 on a PA-T3+, 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-T3+ in a Cisco 7401ASR
router. The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See Table 1-3 for the interface address format.
VIP Interface Addresses
This section describes how to identify the interface addresses used for the PA-T3+ 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 1-3 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 address of the one-port PA-T3+(=)
is 3/1/0 (interface processor slot 3, port adapter slot 1, and interfaces 0). The interface addresses of the
two-port PA-2T3+(=) would be 3/1/0 and 3/1/1 (interface processor slot 3, port adapter slot 1, and
interfaces 0 and1).
Note If you remove the VIP with the one-port PA-T3+(=) from interface processor slot 3 and install it in
interface processor slot 2, the interface address becomes 2/1/0. The interface addresses for the two-port
PA-2T3+(=) would be 2/1/0 and 2/1/1.
