Information
Important Points:
• Spaces between characters are not preserved after entering this command unless you 
enclose the entire description in quotation marks (“desc_text”).
• Entering a text string after the description command overwrites any previous text 
string that you previously configured as the description.
• The shutdown and description commands are the only commands that you can 
configure on an interface that is a member of a port-channel.
• Use the show interfaces description command to display descriptions 
configured for each interface.
