Identifying Interface Addresses
Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-POS-1OC3 in supported platforms.
Interface addresses specify the actual physical location of each interface on a router or switch.
Interface addresses specify the actual physical location of each interface on a router or switch.
Interfaces on a port adapter 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.
