Configuring and Troubleshooting Line Card Interfaces
After the person who installed the hardware verifies that the new line card is installed correctly by
examining the LEDs, the network administrator can configure the new interface. The following sections

Line Card Interface Address
A Cisco ASR 9000 Series Router identifies an interface address by its rack number, line card slot
number, instance number, and port number, in the format rack/slot/instance/port. The rack parameter is
reserved for multirack systems, so it is always 0 (zero) for the Cisco ASR 9000 Series. The line card
slots are numbered from 0 to 7 (Cisco ASR 9010 Router) or 0 to 3 (Cisco ASR 9006 Router).
Instance numbers are reserved for cards that have subslots. This parameter is currently always 0 (zero) for
line cards in the Cisco ASR 9000 Series. The ports on the line card are numbered 0, 1, 2, and so on. For
example, the rack/slot/instance/port address of the fourth port of a line card installed in line card slot 1
is 0/1/0/3. Even if the line card contains only one port, you must use the rack/slot/instance/port notation.

If you perform online insertion or removal of the SFP or XFP module without shutting down the
interface, a warning message is displayed on the console device.
