Chapter 1 Overview
Identifying Interface Addresses
Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-E3 in supported platforms.
Interface addresses specify the actual physical location of each interface on a router or switch.
Interfaces on the PA-E3 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-E3 installed in a VIP or FlexWAN module maintain the same address regardless of
whether other interface processors or modules are installed or removed. However, when you move a VIP
or FlexWAN module to a different slot, the interface processor or module slot number changes to reflect
the new interface processor or module slot.
Note
Interface ports are numbered from left to right starting with 0.
