Configuring the PA-4T+ Interfaces 8-3
Cisco 7200 Series and Cisco uBR7200 Series Ports
Figure 8-1 PA-4T+ Interface Port Address Example—Cisco uBR7246
Figure 8-2 shows the interface ports of a PA-4T+ in slot 2 of the Cisco uBR7200 series. The port
adapter slot are numbered slot 1 and slot 2 (slot 0 is always reserved for the Fast Ethernet porton the
I/O controller—if present). The individual interface port numbers always begin with 0. The number
of additional ports depends on the number of ports on a port adapter. Port adapters can occupy any
port adapter slot; there are no restrictions.
For example, the addresses of the interface ports on the PA-4T+ in chassis slot 2 are 2/0 through 2/3
(chassis slot 2 and interface ports 0 through 3). If the PA-4T+ was in port adapter slot 1, these same
interface ports would be numbered 1/0 through 1/3.

You can identify interface ports by physically checking the slot/port adapter/interface port location
on the back of the router or by using software commands to display information about a specific
interface or all interfaces in the router.
