Extreme Management Center 8.2.5.50 Update Broke SNMPv3 Group on VSPs

Chris_Skelton — Wed, 17 Apr 2019 00:33:25 GMT

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.

Hi there, I wanted to add an update. I have found that by running "Refresh (Rediscover) Device" on a VSP it will delete the SNMPv3 group. I have no idea why this happens now as it never happened before.

I just wanted to post another update to say I have worked around this issue by disabling "Enable Automatic Trap Configuration" in "Administration --> Options --> Trap". I still don"t know what has caused this to become an issue as this setting has always been enabled in our setup. I have opened a support case to try and get a real solution.

Hi Piotr,

Seems to be Ubuntu-related issue. I've found a possible resolution:

Try disabling the apt-cacher service and comment anything you might have configured in
code:
/etc/apt/apt.conf.d/90-apt-proxy.conf

src: https://askubuntu.com/questions/811370/14-04-5-to-16-04-update-failed-xenial-tar-gz-gpg-missing

Let us know if that helped.
Perhaps this service might be used in case of EAC/EAA upgrade (development would have to comment on this) but then you should simply to re-enable the service after an upgrade if disabling it does its job as a workaround.
More about apt-cacher: http://manpages.ubuntu.com/manpages/cosmic/man8/apt-cacher.8.html

Kind regards,
Tomasz
