Junos® OS For Dummies®, 2nd Edition

Displaying Output

The Junos CLI offers you a great deal of flexibility in displaying output. For example, you can request output in different formats, specify how to show more, and pipe (|) the output to display exactly what you want.

Choosing your format

The Junos operational mode show commands commonly include these display options: terse, brief, detail, and extensive (where the commands are listed from the least to the most displayed output). You can use these options to adjust the show output listings according to what you need.

For example, compare the output when adding terse and brief to the following show interfaces command:

wiley@netnik> show interfaces fe-1/1/1 terse
Interface Admin Link Proto Local Remote
fe-1/1/1 up up
at-1/3/0.0 up up inet 1.0.0.1 --> 1.0.0.2
iso
