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).
