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

[AFROJ AHMAD]

Hi ,

SNMP-3-INPUT_QFULL_ERR:   can be because of multiple reasons like : Excessive SNMP polling .

check if they is any host polling this particular device very frequently or multiple host polling the same device at almost same interval.

One of the workaround is to create Access-list allowing SNMP traffic for particular hosts ONLY.

other workaround is below ( these are the most common OID's which can cause issue , you can restrict them from polling ):

you need to configure the SNMP VIEW as below:

snmp-server view cutdown iso included

snmp-server view cutdown at excluded

snmp-server view cutdown ip.21 excluded

snmp-server view cutdown ciscoMemoryPoolMIB excluded

snmp-server view cutdown ciscoEnhancedMemPoolMIB excluded

snmp-server view cutdown ciscoFlashMIB excluded

snmp-server community view cutdown RO

snmp-server community view cutdown RW

Thanks-

Afroz
