Chapter 1 Overview
Identifying Interface Addresses
Catalyst 6000 Family FlexWAN Module
This section describes how to identify the interface addresses used for the PA-4T+ on the
Catalyst FlexWAN module in the Catalyst 6000 family switches. The interface address is composed of
a three-part number in the format module number/port adapter bay number/interface port number.
See Table 1-3 for the interface address format.
If the FlexWAN module is inserted in interface processor slot 3, then the interface address of the
one-port PA-T3+ is 3/1/0 (module number 3, port adapter bay 1, and interfaces 0). The interface
addresses of the two-port PA-2T3+ would be 3/1/0 and 3/1/1 (module number 3, port adapter bay 1, and
interfaces 0 and 1).
Note If you remove the FlexWAN module with the one-port PA-T3+ from interface processor slot 3 and install
it in module number slot 6, the interface address becomes 6/1/0. The interface addresses for the two-port
PA-2T3+ would be 6/1/0 and 6/1/1.
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 7200 Series Routers Interface Addresses
This section describes how to identify the interface addresses used for the PA-T3+ in Cisco 7200 series
routers. 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.
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 address of the interface on the one-port PA-T3+(=) in port adapter slot 1 is
1/0 (port adapter slot 1 and interface 0). If the PA-T3+(=) was in port adapter slot 4, this same interface
would be numbered 4/0 (port adapter slot 4 and interfaces 0).
The interface addresses of the interfaces on the two-port PA-2T3+(=) in port adapter slot 1 are
1/0 through 1/1(port adapter slot 1 and interface 0 or 1). If the PA-2T3+(=) was in port adapter slot 4,
these same interfaces would be numbered 4/0 through 4/1 (port adapter slot 4 and interfaces
0 through 1).
Cisco 7301 Router Interface Addresses
This section describes how to identify the interface addresses used for the PA-T3+ in a 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 1-3 for the interface address format.
1. Slot 1 is reserved for the supervisor engine. If a redundant supervisor engine is used, it must go in slot 2; otherwise, slot 2 can be used for other modules.
2. Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).
