Use the show diag command to determine what type of Fast Ethernet/Ethernet port is active or what type of port adapter is installed in your Cisco 7401ASR router. You can also use the show diagslot command to display information about the port adapter slot. The following example shows the show diag command output from a Cisco7401A SR router. Note that slot 0 is reserved for the native Gigabit Ethernet and Fast Ethernet/Ethernet ports:

Note Both native Gigabit Ethernet and Fast Ethernet/Ethernet ports are reported as Gigabit Ethernet ports. To

select either Gigabit Ethernet or Fast Ethernet/Ethernet ports, use the media-type comman d. See the “Configuring the Native Gigabit Ethernet and Fast Ethernet/Ethernet Interfaces” section on page 3-15.
