Hi, I just want to double check, did you run this command in Traffic Management Shell - tmsh? As if you tried to run this directly in Linux Shell (bash), it won't work. You have to either run the entire command from bash:

 

tmsh modify /sys db tmm.ssl.extmsenabled false

 

Or you have first type tmsh, to enter the TMM shell and then type your command:

 

modify /sys db tmm.ssl.extmsenabled false

 

Here is a link, with more details: https://support.f5.com/csp/article/K66202244
