APM Limited Mode

Hello. As you can see in the screenshot below, we've got APM in limited mode, which should allow to have 10 concurrent sessions. The issue is that we cannot establish any sessions. We get the error: ...

Hello Juan,

In my opinion, APM Limited mode seems to be a bit gimmicky. F5 won't support its use in a production environment, and while this article does say that you can support up to 10 CCUs, I think this is just to give you a small demonstration of APM. Other users that have attempted to use limited APM in a production environment had similar issues, and F5's recommendation was getting a demo Best License, which comes with APM fully provisioned and lasts 45 days. This should give you plenty of time to lab out APM and test functionality.

Should you want to keep working with limited mode, I recommend the following troubleshooting tools:

  1. Check your Active Sessions, as Martjin suggested, by navigating to: Access -> Overview -> Active Sessions. If no sessions are shown, this proves your theory that you cannot establish a session.

  2. Depending on your version of BIG-IP, you can check your license specifications in the CLI. If Limited Mode really does give you 10 free CCUs, you should see them with this:

    tmsh show /apm license

    `

    Will work for versions 12 and above, giving you details about the complete license. For older versions, use the following to check access and connectivity sessions separately.

    `tmsh
show /sys license detail | grep apm_access_sessions
show /sys license detail | grep apm_sessions

More information and specific commands can be found here.

Feel free to ask if you have any follow-up questions,
