Identifying Interface Addresses
Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-5EFL port adapter in supported
platforms. Interface addresses specify the actual physical location of each interface on a router or switch.
Interfaces on the PA-5EFL 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-5EFL 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 1-5
explains how to identify interface addresses.
