Port Addresses
Each port (or interface) in the switch 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 switch 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 switch and its internal
components and software. For more information, see the “Physical Interface
Addresses” section on page 1-85.
Note For Catalyst 6500 series switches running Cisco IOS software, refer to the
Catalyst 6500 Series Switch Cisco IOS Software Configuration Guide for port
address information.
The Media Access Control (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 switches use a
unique method, described in the “MAC Addresses” section on page 1-86, to
assign and control the MAC addresses of their interfaces.
