 Disable broadcast on switch
I wan to permanantly disable broadcast on my 2950 switch. Cos broadcasting causes my network to be down. Is 'broadcast-storm control' the command to use? On the switch I used 4 cables connected to Fastethernet 0/1 to 0/4. If broadcast-storm control is the command to use. What is the level to set? Any examples? Any clues? TIA.
I m using the info here:

broadcasts are part of normal ethernet operation.
switches were created to supress collision domains.
routing can contain broadcast domains.
storm-control won't save you here
redesigning your network will.
nothing can take the place of proper network design.
see patricia oppenheimer's

It's a great book.
I'm studying for the CCDA at the moment and patricia oppenheimer's book is THE perfect compliment.

I can not agree more. Never correct a design problem by adding to it with an additional bad change. Find the source of the problem and correct it! A common error that causes a LAN to go down relates to multicast. For example the default config of the Ghost application is to use multicast and I have seen this down several of our remote site LANs in the past, when a new network person uses it incorrectly. If it were not for other protections we use, those sites may have caused more damage to our entire network rather then just their LAN.
