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.
Note
Interface ports are numbered from left to right starting with 0.
