PA-4T+ port adapter

(interface port addresses 1/0, 1/1, 1/2, 1/3 from left to right)

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 port on 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.
