100% utilization on stack ports

100% utilization on stack ports

Hello we are experiencing 100% utilization on some of our stack ports. I'm new to Extreme network switches so I'm not sure why this is happening. These switches are part of our audio\visual network and when there is 100% utilization, we experience packet loss on some of our stack ports, which affects some of our signage TVs (Blank screens). Any help or pointing me in the right direction would be greatly appreciated. Thanks and please let me know if you require more info.

Hi,

can be looped traffic. Anything suspicious in the log? What about the switches CPU Utilization? Run ELRP in all VLANs on all Ports.

Thanks for your reply. I'll check these things and report back.
