%SNMP-SW1-3-INPUT_QFULL_ERR: Packet dropped due to input queue full

Is there a known bug for this? I found some similar one but its for like 12.x but couldn't find one for 15.x.

If it's not a bug, what's a good way to determine if it's not.

thanks

%SNMP-SW1-3-INPUT_QFULL_ERR: Packet dropped due to input queue f

HI,

Few bugs and it is recorded on csc thread;

CSCsm80154    SNMP stops responding due to %SNMP-3-INPUT_QFULL_ERR

CSCto74586    SNMP - SNMP-3-INPUT_QFULL_ERR when using CISCO-ENERGYWISE-MIB

CSCti48279    %SNMP-3-INPUT_QFULL_ERR needs improvement

CSCth71681    SNMP-3-INPUT_QFULL_ERR, IPCTXERR, and/or CLC unresponsive in SCB

CSCsg60274    Snmp Engine stops responding - Error %SNMP-3-INPUT_QFULL_ERR

CSCtq48275    %SNMP-3-INPUT_QFULL_ERR generated after OIR operations

CSCtn19200    Catalyst6500 generate SNMP-3-INPUT_QFULL_ERR when receive IF-MIB.

What i mean from a genuine issue is when this error in syslog is just a symptom of other issue, like high CPU, device polled extensively or snmp engine not responding at all, etc.

The first thing to try to t/s this is to stop and start snmp engine:

To stop:

no snmp-server

To start:

Any snmp related command which was already configured before stopping snmp engine. You can see snmp configuration using show run | incl snmp-server.

If that does not fix the issue, next step is to take the traceback for SNMP ENGINE PID which i mentioned on last post. traceback can reveal any issue with snmp process.

I had a similar issue on a

I had a similar issue on a 3850 - it is running IOS-XE 3.3.3. Only one SNMP poller and it's Cisco Prime Infrastructure 2.1.

The same IOS is on over 100 other switches of the same model in the network and polled exactly the same and working fine.

Anyhow, stopping and restarting snmp-server as recommended did the trick. Thanks for the tip.

Thanks for getting back to me. I believe I read the same thread. I still haven't found anything specific to version 15.1.
