Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-VXA, PA-VXB, and PA-VXC port
adapters in supported platforms. Interface addresses specify the actual physical location of each
interface on a router or switch.
Interfaces on the PA-VXA, PA-VXB, and PA-VXC port adapters 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.
Note Interface ports are numbered from left to right starting with 0.
Table 1-3 explains how to identify interface addresses.
