Hi there, I just updated our Extreme Management Center to version 8.2.5.50. After the update completed I started to notice all of our VSPs monitoring go offline. Checking the event logs in Extreme Management Center show all of the VSPs with a task run called "SNMP Set Success" followed by "snmpTargetSpinLock.0 [0]", snmpTargetSpinLock.0 [1], or snmpTargetSpinLock.0 [2]. I don't know why this task ran as I have updated Extreme Management Center several times with no issues prior. After investigating the VSPs it turns out that the USM group membership was removed so it broke the SNMPv3 credentials.
I just wanted to post this to see if anyone else has experienced this issue yet. I know this patch just came out so I don't expect much of a response.
