====== NIC Link Status ======
\\ 
\\ 
To show the Link Status on an interface (Speed, Duplex, MDIX etc) we can use the <color red>ethtool</color> command.
\\ 
\\ 
From the command line enter:
\\ 
    /sbin/ethtool ethx (where x is the interface number)
\\ 
\\ 
Example:
\\ 
    /sbin/ethtool eth4    (in this example, eth4 is connected to a Cisco 3560G switch)
