Identifying Interface Addresses - Cisco PA-POS-2OC3 Installation And Configuration Manual

Identifying Interface Addresses

Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-POS-2OC3 in supported platforms.
Interface addresses specify the actual physical location of each interface on a router or switch.
Interfaces on a PA-POS-2OC3 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-POS-2OC3 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.
Interface ports are numbered from left to right starting with 0.
