Cisco 7100 Series Ports
In the 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 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 the Cisco 7120 series routers are numbered as shown in Figure 8-2. The fixed LAN interface
is slot 0, the fixed WAN interface is slot 1, and the modular port adapter interface is slot 3. Slots 2
and 4 are not used in the Cisco 7120 series. Slot 5 is the service adapter.
