Broadcast storm control alerting

Hi,

I would like to set up broadcast storm control an a 2950 as follows:

interface FastEthernet0/1

port storm-control broadcast trap

port storm-control broadcast threshold rising 20 falling 10

switchport access vlan 547

This works OK, but I am not able to see any traps. I have tested it and know it does work, but I am unable to see the traps. Logging is enabled for all messages and I am getting some messages on my syslog, but none related to the broadcast storm control.

What do I need to do??

Thanks.

Hi,

these traps are not syslog but SNMP ones.

See http://www.cisco.com/univercd/cc/td/doc/product/lan/cat2950/12119ea1/2950scg/swsnmp.htm#1043530

for instructions how to configure them.

Re: Broadcast storm control alerting

Hi Milan,

Below is a list of the traps I am sending to my CiscoWorks server.

snmp-server community public

snmp-server chassis-id SW1

snmp-server enable traps snmp authentication linkdown linkup coldstart

snmp-server enable traps config

snmp-server enable traps entity

snmp-server enable traps hsrp

snmp-server enable traps c2900

snmp-server enable traps vlan-membership

snmp-server enable traps vtp

snmp-server enable traps cluster

snmp-server host 10.1.1.2 trap private

Where would I check for the SNMP traps in CiscoWorks?

Re: Broadcast storm control alerting

Go to Device Fault Manager -> Monitoring Console.

You can also download a Device Fault History from CCO for an additional functionality.

Re: Broadcast storm control alerting

So what's the difference between an SNMP trap and and SNMP inform? is it just the severity?
