Link Down - Only recourse is to reboot (6.40.3 on x86)

Hi All,

I have a hotspot server with a campus wide bridge servicing several buildings. Each building has a switch plugged to their own port on the hotspot controller.

Recently I have had an issue where an entire building will go down. Only rebooting the controller will re-enable the bridge port.

I thought it was an STP issue at first but don’t see any info in the logs.

Enabling/disabling the port does not work - only rebooting the entire controller.

I’m on 6.40.3 and have replaced the hardware - still there.

Has any new features/bugs - this setup has run fine since 2014.

Thanks!
