 +==== Show Interface ====
 +\\ 
 +Show Interface displays detailed information about each interface. If you only issue the command <color #00a2e8>sh interface</color> (Nexus) <color #00a2e8>(or sh interfaces for IOS)</color> then you get information regarding all interfaces.
 +\\ 
 +\\ 
 +You can get information on a specific interface by using the Cisco syntax <color #00a2e8>sh interface ethernet 1/1</color>. In this example we get the information for port 1. Depending on your switch you might have to use <color #00a2e8>ethernet</color> or <color #00a2e8>GigabitEthernet</color> etc.
