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
