Chapter 1 Overview
Identifying Interface Addresses
Note
Interface ports are numbered from left to right starting with 0.
Table 1-4
explains how to identify interface addresses.
Cisco 7100 Series Routers Interface Addresses
This section describes how to identify the interface addresses used for the PA-4R-DTR 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
Table 1-4
for the interface address format.
Cisco 7200 Series Routers Interface Addresses
This section describes how to identify the interface addresses used for the PA-4R-DTR 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 1-4
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-4R-DTR in port adapter slot 1 are
1/0 through 1/3 (port adapter slot 1 and interfaces 0 through 3). If the PA-4R-DTR was in port adapter
slot 4, these same interfaces would be numbered 4/0 through 4/3 (port adapter slot 4 and interfaces
0 through 7).
