Identifying Interface Addresses
This section describes how to identify interface addresses for the PA-8T-V.35 in supported platforms.
Interface addresses specify the actual physical location of each interface on a router or switch.
Interfaces on the PA-8T-V.35 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-8T-V.35 installed in a Catalyst 6000 family FlexWAN module or a VIP maintain the
same address regardless of whether other interface processors are installed or removed. However, when
you move a Catalyst 6000 family FlexWAN module or 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.
