M4300 Broadcast UDP Dropping Fragments

I've got a strange one here..... I have some specific traffic from a media server which is transmitting UDP between PCs. All is well when only 1 machine is listening as the media server runs this ...

Hi KCrouch ,

 

We would need the tech-support file to better understand your issue, never hesitate to reach out to ProAVDesign@netgear.com by email for us to help you.

 

But at first glance like that, just try to disable Broadcast Storm Protection going to Security\Traffic Control\Storm Control. I wouldn't disable Broadcast Storm Protection globally, but you can go to \Storm Control Interface Configuration, select the ports where your server and your receivers are, and put Disable in Recovery mode. Click Apply and if goes well, save your configuration in the upper right (disk icon)?

 

I hope this will help,

That looks like it has fixed it. I need to double check with the proper equipment but in the lab setup I was able to replicate the issue with a 16K ping and then when I disabled recovery or pushed the threshold to 30% my ping was working.

 

Is there anyway of applying this on a IP level (ie any broadcast from a specific address gets a different threshold)?

 

Thanks again for the help

    Glad the Broadcast Storm Protection disablement or different threshold fixed this issue for now.

    No, Storm Protection can only be configured globally, or at the physical interface (port) level.

     

    If you want to manage that differently, by IP etc. then you could disable Broadcast Storm Protection on all ports where you intend big broadcast like that - and use ACLs to restrict the bandwidth. Advanced IP ACLs with source/destination IP can be configured with traffic rate and burst; then you can bind the ACL to the ports where you disabled the Storm Protection.

     

    Thanks!
