3550: broadcast storm

I would like to know, how can i find out if there is broadcast storm on my cat3550.

could this be used? "sh mac-address-table multicast"

or I need to setup a "ip account"

pls advise.

Re: 3550: broadcast storm

Hello Jason,

a broadcast storm means that usually there is a very high amount of dropped traffic. If you suspect a broadcast storm check your interfaces for those errors. You can also install a sniffer (e.g. the Ethereal sniffer, free to download at www.ethereal.com), or check the following website for more sniffers:

Re: 3550: broadcast storm

in that case, this is not i'm looking for. but wanna know, if someone says that they suspect there is virus on our network. how could i determine that! my colleague told me to do "sh ip account" does that help?

Looking at IP Accounting stats can help if IP Accounting is enabled, but your best bet is probably some type of sniffer attached to a SPAN port.
