packet rate extremely high and crash my network

ALL

some of my tenant may have virus, or something, and let the packet rate to very high, and the traffic to internet, and crash the firewall also.

what i can do for those trunk or switchport in order to lower the risk.

i had try to stormcontrol broadcast to 2%, but seem not to the problem.

Re: packet rate extremely high and crash my network

I dont know if this is 100% relevant to your scenario but the link below

http://www.cisco.com/en/US/products/sw/iosswrel/ps1835/products_tech_note09186a0080110d17.shtml

describes a mechanism to protect networks against the nimda virus.

It uses QoS and CAR to achieve this.

A more long term solution in your case would be to isolate each of the "tenants" on their individual private vlans in isolated mode and have the router in promiscuous mode which would limit the broadcasts between the hosts themseleves and create a one way channel between each host and the router. This is of course for those clients that do cause havoc on the network. The rest of them could remain in the same vlans :)

Here is a link that might help
