Chapter 1 Overview
Identifying Interface Addresses
Cisco 7507 routers have five slots for port adapters, and two slots for RSPs. The slots are numbered from
left to right. You can place a port adapter in any of the VIP interface slots (slot 0, 1, 4, 5, or 6). Slots 2
and 3 are always reserved for RSPs. The Cisco 7507 router is not shown.
Cisco 7513 routers have eleven slots for port adapters, and two slots for RSPs. The slots are numbered
from left to right. You can place a port adapter in any of the VIP interface slots (slots 0 through 5, or
slots 9 through 12). Slots 6 and 7 are always reserved for RSPs. The Cisco 7513 router is not shown.
Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-8E in supported platforms.
Interface addresses specify the actual physical location of each interface on a router or switch.
Interfaces on the PA-8E installed in a router maintain the same address regardless of whether other
port adapters are installed or removed. However, when you move a port adapter to a different slot, the
first number in the interface address changes to reflect the new port adapter slot number.
Interfaces on the PA-8E installed in a VIP or FlexWAN module maintain the same address regardless of
whether other interface processors or modules are installed or removed. However, when you move a VIP
or FlexWAN module to a different slot, the interface processor or module slot number changes to reflect
the new interface processor or module slot.
Note Interface ports are numbered from left to right starting with 0.
