Chapter 1 Overview
Identifying Interface Addresses
Catalyst 6000 Family FlexWAN Module Interface Addresses
In Catalyst 6000 family switches, the Catalyst 6000 family FlexWAN module can be installed in module
slots 2 through 13 (depending on the number of slots in the router). Slot 1 is reserved for the supervisor
engine. A port adapter can be installed into either port adapter bay 0 or bay 1 on a FlexWAN module.
See
.
The interface address is composed of a three-part number in the format
module-number/port-adapter-bay-number/interface-port-number. See
.
The first number identifies the module slot of the chassis in which the FlexWAN module is installed (slot
2 through slot 3, 6, 9, or 13 depending on the number of slots in the chassis). These module slots are
generally numbered from top to bottom, starting with 1.
The second number identifies the bay of the FlexWAN module in which the port adapter is installed
(0 or 1). The bays are numbered from left to right on the FlexWAN module.
The third number identifies the physical port number on the port adapter. The PA-E3 is a single-port port
adapter, therefore the port is always 0. The PA-2E3 is a dual-port port adapter, therefore the port can be
0 or 1.
For example, if a single-port PA-E3 is installed in a FlexWAN module in module slot 3, port adapter bay
0, then the interface address is 3/0/0 (module slot 3, port adapter bay 0, and interface 0). I f a dual-port
PA-2E3 is installed in a FlexWAN module in module slot 3, port adapter bay 0, then the interface
addresses are 3/0/0 and 3/0/1 (module slot 3, port adapter bay 0, and interfaces 0 and 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 7100 Series Routers Interface Addresses
In Cisco 7120 series router, port adapters are installed in port adapter slot 3. See
. In the Cisco
7140 series router, port adapters are installed in port adapter slot 4. See
.
The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See
. For example, if a single-port PA-E3 is
installed on a Cisco 7120 router, the interface address would be 3/0. If a dual-port PA-2E3 is installed
on a Cisco 7120 router, the interface addresses would be 3/0 and 3/1. If a single-port PA-E3 is installed
on a Cisco 7140 router, the interface address would be 4/0. If a dual-port PA-2E3 is installed on a
Cisco 7140 router, the interface addresses would be 4/0 and 4/1.
Cisco 7200 Series Routers and Cisco 7200 VXR Routers Interface Addresses
In Cisco 7200 series routers and Cisco 7200 VXR routers, port adapter slots are numbered from the
lower left to the upper right, beginning with slot 1 and continuing through 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
adapters can be installed in any available port adapter slot from 1 through 6 (depending on the number
of slots in the router). (Slot 0 is reserved for the I/O controller.) See
The interface address is composed of a two-part number in the format
port-adapter-slot-number/interface-port-number. See
. For example, if a single-port PA-E3 is
installed in slot 1of a Cisco 7200 series router, the interface address would be 1/0. If a dual-port PA-2E3
were installed in slot 1, the interface addresses would be 1/0 and 1/1.
