Juniper devices have extensive help options in the CLI.
Tip of the day
To view a very short tip, execute:
marios@juniper> help tip cli
This is not exactly a tip of the day - since you actually get a new tip each time you execute that command. Still pretty cool though.
Help with syslog messages
You can view an explanation of what a syslog message means with help syslog. For example, for the LOGIN_INFORMATION
message, execute:
marios@juniper> help syslog LOGIN_INFORMATION
Search in help topics
You can search in help topics with help apropos. This will return a list of help pages that contain the word you
searched for. For example, you can search for all pages that refer to syslog with:
marios@juniper> help apropos syslog
Topical help
To get help on a specific topic, start with help topic. For example, for help on syslog, execute:
marios@juniper> help topic system syslog
