Abstract
A packet switch collects configuration information on the peer devices to which it connects. Peer devices that are IP (Internet Protocol) telephones are sensed. Such devices may also bridge packets to a connected device such as a computer, but with a bridge capability that cannot handle large broadcast storms on the network. The packet switch uses the configuration information to limit broadcast storms on its ports connected to the relatively fragile IP telephones/bridges. This can prevent broadcast storms from disrupting calls on the IP telephones connected to the packet switch.
