Overview
Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-MC-2T3+ in supported platforms.
Interface addresses specify the actual physical location of each interface on a router or switch.
Interfaces on the PA-MC-2T3+ 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-MC-2T3+ 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.
Interface ports are numbered from left to right starting with 0.
