Broadcasts !!

[Hari Vishnu]

Hi,

Can anyone please tell me in which scenarios layer 3 and layer 3 broadcast is generated and how we can find the source and prevent them. We have a case where the LAN interface of the router is receiving lot of broadcasts, have created one ACL to log all the outgoing traffic. I could see some L3 broadcast(ie traffic destined to 10.0.0.255) sourced from different machines. Does that add to the broadcast count under interface ?

Thanks,

Hello,

Just shooting across here, have you checked for loops and/or configured storm control on your switches?

Also check for rogue dhcp servers as well as possible botnets/smtp mail infections.
