CPU issue, high switch process

Mon Feb 13, 2023 2:18 pm

We are having a problem with one of our switches. It reports high traffic and high cpu usage. Connected devices don't match the amount of traffic it reports in the webui.
All discovery and snmp are disabled.

For example the upstream router is sending 130Mbps (all APs combined), the downstream AP is receiving 20Mbps according to those devices. The Wispswitch shows it is sending and receiving ~700Mbps on the port to that AP...

What is wrong and how can we resolve this issue?

We are experiencing the same problem. Switch CPU usage was pegged at 99% and killed connection to one port.
It happened twice on the WS-26-DC switch with Firmware Version: 1.5.12.
Rebooting switch helps but definitely not permanent solution.
