PA-2FEISL 100BASE-T Fast Ethernet/ISL Port Adapter Installation and Configuration

Chapter 1 Overview
Identifying Interface Addresses
shows port adapters installed in slot 1 and slot 2 of a Cisco uBR7246 router. The
port adapter slots are numbered slot 1 and slot 2 for the Cisco uBR7246, and slot 1 for the
Cisco uBR7223 and the Cisco uBR7246 VXR. (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-2FEISL in port adapter slot 2 are 2/0 and 2/1
(port adapter slot 2 and interfaces 0 and 1). If the
PA-2FEISL 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).
VIP2 Interface Addresses
This section describes how to identify the interface addresses used for the PA-2FEISL on a VIP2 in
Cisco 7000 series and Cisco 7500 series routers.
Note
Although the processor slots in the 7-slot Cisco 7000 and Cisco 7507 and 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
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
.
shows a sample Cisco 7505 system. The interface addresses of the
PA-2FEISL are 3/1/0
through 3/1/1). If the port adapter was in port adapter slot 0 on the VIP2, these same interface addresses
would be numbered 3/0/0 through 3/0/1.
If you remove the
VIP2 with the
PA-2FEISL
(shown in
) from interface processor slot 3 and
install it in interface processor slot 2, the interface addresses become 2/1/0 through 2/1/1.

Note
If you remove the PA-2FEISL-equipped VIP2 (shown in
) from interface processor slot 3 and
install it in interface processor slot 2, the interface addresses become 2/1/0 through 2/1/1.
