Chassis Slot and Logical Interface Numbering

In Cisco 7100 series VPN routers, the slot number is the location in the chassis where the interface
resides and the port number is the physical port associated with that slot. Cisco 7100 series router slots
are numbered 0 through 5. Interfaces in the Cisco IOS software are identified by a type, slot number, and
port number. The number of physical ports depends on the type of modular port adapter or fixed
interface. For example, in a Cisco 7120-4T1, serial 1/0 indicates port 0 on the fixed serial interface in
slot 1. (See
