Cisco 7100 Series Ports

In Cisco 7100 series routers, the slot number is the location in the chassis where the interface resides and the port number is the physical port. Interfaces in the Cisco IOS software are identified by a type, slot number, and port number. For example, serial 3/1 indicates port 1 on the serial port adapter in slot 3.

Slots in Cisco 7120 series routers are numbered as shown in Figure 8-4. The fixed LAN interface is slot 0, the fixed WAN interface is slot 1, and the modular port adapter interface is slot 3. On the Cisco 7120 series, slots 2 and 4 are not used. Slot 5 is the service adapter.

Shutting Down an Interface

Before you replace an interface cable, replace port adapters, or remove an interface that you will not replace, use the shutdown command to shut down (disable) the interfaces. Doing so prevents anomalies from occurring when you reinstall the new or reconfigured port adapter. When you shut down an interface, it is designated administratively down in the show command displays.

Follow these steps to shut down an interface:

Step 1 Enter the privileged level of the EXEC command interpreter. (See the “Using the EXEC Command Interpreter” section on page 8-1 for instructions.)
