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
To identify port adapter slots and the Port Adapter Jacket Card and to obtain information about the port adapters, use the show diag command.
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.
