CirrusShould config via cli rather than gui?
hi, someone advised to better config big-ip via cli rather than gui, and for HA cluster, should config on standby unit rather than active unit. Are these advices correct? if yes, why need to do so? ...
- It is recommended to use the GUI whenever possible. For me, when I make a lot of changes at once I use the CLI because it's faster but if it's just a few changes I will perform them in the GUI.
- If you have your HA cluster setup to auto-sync the configuration between devices it doesn't matter if you make the changes on the active or standby unit. If you made the changes on the standby unit you theoretically have a slight delay for the changes to sync to the primary unit.
Food for thought. A lot of the F5 certificate questions are GUI based so it would be better in the long run to make the changes in the GUI.

AltostratusI agree with Aswin on management, configuration, and troubleshooting.
Regarding HA, I would say you must configure changes on the active chassis to see the impact of the change. If you make a change on the standby chassis, you cannot confirm whether it works fine or not.
Also, we have two options for configuration sync: Automatic and Manual. If you use the Manual option, it provides a safer way to roll back the configuration. Make the change on the active chassis first; if everything works well, you can sync the configuration. Otherwise, you can sync the configuration from the standby chassis to the active one.
