Query Related to License

HI Friends,

While checking license of BIG-IP LTM and GTM. I am getting below output on GUI and CLI.

Output On GUI :

For LTM :

License Type : Production

Licensed date : Nov 10, 2017

And there is list of some modules under ACTIVE MODULES section.

For GTM :

License Type : Production

Licensed date : Dec 23, 2012

Showing Active Module :

 Global Traffic Manager Module

  STP

  GTM, DNS LB

  DNS Express

There are some Optional Modules in GTM GUI output as well:

which Contains, ASM, AFM, PSM, Link Controller, WAN, WOM, MSM, Routing Bundle and many more.

QUERY : What is the Licensed Date here meaning (which is 10-Nov-2017 and 23-Dec-2012) , What is the OPTIONAL MODULES means, Are License taken for this as well.

• Here in CLI i am not getting Optional Module in LTM as in GTM output.
• What is "Licensed on" & "Service Check Date" are ? (in CLI output) , Both showing different dates

How to Validate, which are all Modules (for which License is purchased) are "Actively used".

Regards
