Limited bandwidth on Virtual Edition

Hi.

We have a Virtual Edition license here for developpement. This device is limited to 10Mbps.

My problem is that the log is full of messages like this :

...

How can I configure the F5 to just shape the traffic and stop logging about it ?

Thanks in advance !

    Thanks for your response.

     

    You are right, for a developpement box that is not a problem. But I'm actually having issues and those lines make reading logs harder.

     

    I have Bandwidth controller. I made a new entry, but it did not seems to change anything.

      Most likely not properly configured. Good idea to read the manual carefully, including any applicable caveats. Also, it is easy to filter unwanted logs using "grep". `grep /var/log/ltm | grep -v "Bandwidth utilization"` The above command will display the ltm log file without all bandwidth utilization messages.

    Another possible reason is that you are using LAB license that is limited at 10 Mbps throughput.

     

    In that case you have nothing to do with that particular VE.

     

    If you need to perform some tests with a bigger data volume you can try to contact your local sales representative and ask for VE Strongbox (eval) license with 200M or 1G (or even more) throughput.

      The messages are well understood. User wants to prevent them from happening...

      I'm curious on F5 view.

       

      We do a lot of soak testing of software with the F5 in front, and are hitting this routinely.

       

      Poor tester today... ... exceeded the user test limit on some software by having too many concurrent test users. ... exceeded the network limit on the F5.

       

      Is the traffic shaped & restricted to this? If we ask nicely will they let us test at full throttle. We mostly test without the F5, but anything we can do to make it more like our live deployment within reason.
