Identifying Interface Addresses
Cisco 7304 Router Interface Addresses
This section describes how to identify the interface addresses used for the OC12 POS line card in a
Cisco 7304 router. The interface address is composed of a two-part number in the format
slot-number/interface-port-number. See
for the interface address format.
In a Cisco 7304 router, slots are numbered, beginning with slot 0 (a dual-width slot reserved for the
NSE-100) on the bottom, and continuing from the lower left to the upper right through slot 5.
Note
The NSE-100 is the only card supported in slot 0.
The interface address of the interface on an OC12 POS line card in slot 2 is 2/0 (slot 2 and interface 0).
If the OC12 POS line card was in slot 4, this same interface would be numbered 4/0 (slot 4 and
interface 0).
