SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input on cisco WS-C3850-48P switch.

[Hitesh Mehta]

I have a 3850 switch which is not being polled in tool due to below snmp error. May I know is there any solution to get rid of it apart from the upgrade.

I have the same problem and I restarted the SNMP agent >> no snmp server

%SNMP-3-INPUT_QFULL_ERR: Packet dropped due to input

I am running a CISCO 3850

Is the solution to upgrade the IOS?

Hi,

Did you manage to resolve this?

I seem to be experiencing this issue on my 3850 stack (Version 03.02.03.SE). Restarting the SNMP engine only clears the error for a few minutes.

Thanks
