control SNMP Traps traffic

Hardish Thacker — Wed, 17 Mar 2010 09:39:28 GMT

I have Procurve 8212zl and 5412zl switches. I had enabled SNMP on these switches and I am getting traps on my NMS system. I want to restrict these traps for few interfaces only. For example, I wan to monitor only tagged ports and some server ports only. remaining are not interested. How can I make it?

Hi,

You can disable traps for certain interfaces with the command

no snmp-server enable traps

For example, to stop receiving traps for dhcp-snooping events on port A1 you set:

no snmp-server enable traps dhcp-snooping A1

My switch contain approx 400 ports and it's not only one switch with this capacity. I want to monitor only 60-70 ports out of 2000. Is there any way for bulk management?

Well if, for example, you're talking about link-change traps you can disable traps for all ports with:

no snmp-server enable traps link-change all

and then just enable the ones you want.

You can also set the level of traps sent with the command:

snmp-server host

it really depends on what traps you want to restrict.
