SNMP Traps

If i will enable all the SNMP traps instead of enabling some specific traps. Will there be any effect on the device performance or network performance?

What is recommended either we have to enable specific traps or all the traps of SNMP?

If you enable all SNMP traps

If you enable all SNMP traps then obviously there will be some increase in CPU to process all of the traps and some increase in network bandwidth utilization to transmit the greater number of traps. Whether those increases will be significant or not depends on the device environment. If it is a small device in a quiet part of your network that processes a low volume of traffic probably a very small impact. If it is a busy device in the core of your network with lots of services enabled probably a larger impact.

 

Without knowing more about your environment it would be difficult to provide a recommendation.

Hi Mukesh,As said we cant say

Hi Mukesh,

We cannot predict how much the percentage would be,  it depends on the number of traps that the device generates/sends. hence we cannot say exact %percentage of link utilization.

Saying that make sure you only configure the required SNMP and not all , By using all the SNMP paramenters the device sometime will end up eating all cpu resources and you would need to troubleshoot high cpu on the device caused due to SNMP engine.

Hello Richard,Thanks for the

Hello Richard,

Thanks for the information.

I am having 3750 switches in my network. I just want to know how much will be the bandwidth utilization by all the SNMP traps?
