Chapter 1 Overview
Identifying Interface Addresses
See
for the interface address format.
If the FlexWAN module is inserted in module slot 3, then the interface addresses of the PA-8T-232 are
3/0/0 through 3/0/7 (module slot 3, port adapter bay 0, and interfaces 0 through 7). If the port adapter
was in port adapter bay 1 on the FlexWAN module, these same interface addresses would be numbered
3/1/0 through 3/1/7.
Note
If you remove the FlexWAN module with the PA-8T-232 from module slot 3 and install it in module slot
6, the interface addresses become 6/0/0 through 6/0/7.
Note
The FlexWAN module physical port address begins with slot 0, which differs from the conventional
Catalyst 6000 family port address, which begins with slot 1.
Cisco 7100 Series Routers Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-232 in Cisco 7100
series routers. The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See
for the interface address
format.
Cisco 7200 Series and Cisco uBR7200 Series Routers Interface Addresses
This section describes how to identify the interface addresses used for the PA-8T-232 in Cisco 7200
series routers or Cisco uBR7200 series routers. The interface address is composed of a two-part number
in the format port-adapter-slot-number/interface-port-number. See
for the
interface address format.
In Cisco 7200 series routers, port adapter slots are numbered from the lower left to the upper right,
beginning with port adapter slot 1 and continuing through port adapter slot 2 for the Cisco 7202, slot 4
for the Cisco 7204 and Cisco 7204VXR, and slot 6 for the Cisco 7206 and Cisco 7206VXR. (Port
adapter slot 0 is reserved for the optional Fast Ethernet port on the I/O controller—if present.)
The interface addresses of the interfaces on the PA-8T-232 in port adapter slot 1 are 1/0 through 1/7
(port adapter slot 1 and interfaces 0 through 7). If the PA-8T-232 was in port adapter slot 4, these same
interfaces would be numbered 4/0 through 4/7 (port adapter slot 4 and interfaces 0 through 7).
In Cisco uBR7200 series routers, port adapter slots are numbered slot 1 and slot 2 for the
Cisco uBR7246 and Cisco uBR7246VXR and slot 1 for the Cisco uBR7223. (Slot 0 is always reserved
for the Fast Ethernet port on the I/O controller—if present.) The individual interfaces always begin with
0. The number of additional interfaces depends on the number of interface ports on a port adapter.
The interface addresses of the interfaces on a PA-8T-232 in port adapter slot 2 are 2/0 and 2/1
(port adapter slot 2 and interfaces 0 and 1). If the PA-8T-232 was in port adapter slot 1, these same
interfaces would be numbered 1/0 and 1/1 (port adapter slot 1 and interfaces 0 and 1).
