(You'll probably have more luck generating discussion on a Cisco-related list or newsgroup.) My advice is to ascertain why packet storms are occurring on your network and then work on eliminating them as close to the source as possible. Switch level controls can be useful, but they're more of a bandaid than a fix. Broadcast/multicast storms generally shouldn't be happening in the first place (and unicast storms definitely shouldn't be happening) so it may be beneficial to look at this from a design point of view -- if the packet storms are the result of a broken network or broken hosts, switch level rate limiting isn't the optimal solution. -Terry

I have a large network with an installed base of various Cisco switches and routers. Upon doing some research the only way I can find to limit the effect of a broadcast storm is to use the port based command storm-control. While this is feasible, but time consuming, I would like to find a solution that can be performed either for the entire switch, access router or preferably from the distribution level of the network. Any ideas would be appreciated. _______________________________________________ firewall-wizards mailing list firewall-wizards () honor icsalabs com http://honor.icsalabs.com/mailman/listinfo/firewall-wizards
