SNMP contact lost after upgrade

[Justsomebodi]

We have upgraded a number of X460 stacks from release 15.3.1.4 to 16.1.1. I now have a single switch that has no SNMP contact. I am aware of an issue on the forum with previous release upgrades causing a problem, but my SNMP settings look fine.

Hi Justsomebodi,

I also have this same problem. But it's happening in version 15.7.I'm already an open ticket in GTAC.

Let you have a question, what is your SNMP management system? CA System? Or Other?

If you want to resolve this issue quickly the suggestion is to downgrade to version 15.6.3.1 patch1-8.

I confess I did not have this problem with NetSight.

But I suspect that the SNMPMaster process does not catch, try increasing the idle-timeout time in NetSight to see if it to lose communication with the switch.

And I realized that in my case, when I do an SNMP REQUEST to the switch responds with delay SNMP RESPONSE. This time may take less than 1 second to 1 minute and 30 seconds.

But when you do the command "restart process snmpmaster, starts fast answer at first, but then responds to SNMP requests with delay.

Hi we use Netsight. Downgrade isn't an option at the moment.
