Looks like a real hardware fault to me. Time to replace the switch.

Subject: [e-nsp] Summit5i problem ?

Take a look at log below.
Result - 90% packet loss, even management via regular port was almost
impossible.
After restart - switch works fine, but...
Is it a real hardware fault or could be some fault @ ASIC programming ?

Regards,
Marcin

Looks like CRC error within the backplane. Could be an hardware failure, did you run an extended diagnostic?

hi, i am experiencing somthing really similar, seeming to disapear after
reboot too , so i am interested, how things are going on for you ?

Is this really a hardware failure coming or would this be possible to come
from some type of DoS or from some faulty heavy network trafic ?

When I used to deal with Extreme, they always claimed these type of
messages were indicative of a hardware problem.

The best thing to do in my opinion would be to run extended diags a few
times, if they come back normal then consider the switch "OK" but do keep
an eye on it.

If this switch is critical and can't afford any downtime, then ignore the
above and consider it faulty :)
