Identifying Interface Addresses

This section describes how to identify interface addresses for the PA-4T in supported platforms. Interface addresses specify the actual physical location of each interface on a router or switch.

Interfaces on the PA-4T 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 a PA-4T installed in a VIP maintain the same address regardless of whether other interface processors are installed or removed. However, when you move a VIP to a different slot, the interface processor slot number changes to reflect the new interface processor slot.

Note Interface ports are numbered from left to right starting with 0.

Table 1-8explains how to identify interface addresses.

Table 1-8	Identifying Interface Addresses
Platform		Interface Address Format	Numbers	Syntax
Cisco 7200 series routers		Port-adapter-slot-number/interface-port-number	Port adapter slot—0 through 6	1/0
			(depends on the number of slots
			in the router)1
			Interface port—0 through 3
VIP in Cisco 7500 series		Interface-processor-slot-number/	Interface processor slot—0	3/1/0
routers		port-adapter-slot-number/interface-port-number	through 12 (depends on the
			number of slots in the router)
			Port adapter slot—always 0 or 1
			Interface port—0 through 3

1. Port adapter slot 0 is reserved for the Fast Ethernet port on the I/O controller (if present).
