Identifying Interface Addresses
The following sections describe the interface address formats for specific platforms. Interface addresses
specify the actual physical location of each interface on a router or switch.
Interfaces on the PA-2FE 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-2FE 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.
