Hello,

I guess you already tried to reboot and test again?

Personally I would use the new 31.x firmware only for the switches where you currently need it: The 5520. For all other switches I recommended 30.7.1.1-patch1-54 or patch1-86. Have it on several hundred switches - no problems. 31.x generally seems to have a few problems.

I am having the same problem but with EXOS 30.7.1.1 patch 1-54 installed. SSH was working when I setup the switch but ssh stopped working after a reboot… and no rebooting again did not fix it.

Would appreciate anything we can try, otherwise will open a ticket with GTAC I guess.

Thanks
