Mapping Interfaces and Physical Ports
Table 2-2 maps the cable interface card’s interfaces and physical ports. The cards can be configured in
a number of different upstream combinations.
Identifying Port Adapter Slots
On the Cisco uBR7100 series universal broadband routers, two port adapter slots are available. Slot 0 is
the fixed FastEthernet interface, and slot 3 is the modular port adapter. You can display information on
a specific port adapter or all port adapters in the Cisco uBR7100 series router. To display information
about all port adapter slots, use the show interfaces command. To display information about a specific
port adapter slot, use the show interfaces command with the port adapter type and slot number in the
format of show interfaces [type slot/port].
Tip If you abbreviate the command (sh int) and do not specify the port adapter type and slot number (or
arguments), the system interprets the command as show interfaces. The system displays the status of all
port adapters, all cable interface cards, and all ports.
Following is an example of how the show interfaces command displays status information (including
the physical port adapter number) for each port adapter and cable interface card in the Cisco uBR7111:
