ip description name
no ip description
Command introduced before JUNOSe Release 7.1.0.
Assigns a text description or an alias to a static IP interface or subinterface. If no IP interface currently exists, then a static IP interface is automatically created on the current layer 2 interface and the description is applied to that static IP interface. You cannot assign a profile to a layer 2 interface that has a static interface configured above it. Use the show ip interface command to display the text description. The no version removes the description or alias.
Note: This command is replacing the description command to assign a description to a static IP interface. The description command may be removed completely from Interface Configuration mode in a future release.
