The Media Access Control (MAC) address or hardware address is a standardized data link layer address
that is required for certain network interface types. These addresses are not used by other devices in the
network; they are specific and unique to each port. The Cisco 7200 VXR routers use a specific method
to assign and control the MAC addresses of its port adapters. For a description of the MAC address, see
the "MAC Address" section on page
Port adapter slots maintain the same slot number regardless of whether other port adapters are installed
or removed. However, when you move a port adapter to a different slot, the port adapter slot number
changes to reflect the new slot number.
You can identify port adapter slots by using software commands. To display information about all port
adapter slots, use the show interfaces command. To display information about a specific port adapter
slot, use the show interfaces command with the port adapter type and slot number in the format
show interfaces port-adapter-type slot-number/port-number. If you abbreviate the command (sh int)
and do not specify port adapter type and slot number (or arguments), the system interprets the command
as show interfaces and displays the status of all port adapters and ports.
The following example shows how the show interfaces command, used without arguments, displays
status information (including the physical port adapter number) for each port adapter in a
Cisco 7206VXR.
In the following example, most of the status information for each interface is omitted.
