I believe that when the 2900's boot up without an IP address (on vlan1) they will try to get one using BootP. If you give vlan 1 an IP address (even a bogus one if you are not using that vlan) it should stop the broadcasts.

However, the broadcast problem disappear after I move out the vlan1 machines into another newly created Vlan (vlan 4), after I had shutdown Interface Vlan 1. Can anyone care to enlighten me? Thanks.
