Port Addresses

Each port (or interface) in the Cisco 7600 series router is designated by several different types of
addresses. The physical interface address is the actual physical location (slot and port) of the interface
connector within the chassis. The system software uses the physical addresses to control activity within
the system and to display status information. These physical slot and port addresses are not used by other
devices in the network; they are specific to the individual router and its internal components and
software. For more information, see the
The MAC address is a standardized data link layer address that is required for every port or device that
connects to a network. Other devices in the network use these addresses to locate specific ports in the
network and to create and update routing tables and data structures. The routers use a unique method,
described in the
their interfaces.

Physical Interface Addresses

Physical port addresses specify the actual physical location of each module port on the rear of the router,
as shown in
nine-slot, and thirteen-slot chassis.) The address is a two-part number in the format slot/port number.
The first number identifies the slot in which the module is installed. Module slots are numbered from
right to left starting with 1. The second number identifies the physical port number on the module. The
port numbers always begin at 1 and are numbered from top to bottom. The number of additional ports
(n/1, n/2, and so on) depends on the number of ports on the module.
