ABSTRACT:
An apparatus and method for controlling bridge protocol data unit bursts is disclosed. The invention in the preferred embodiment is a switching device with a port enabled with a link management protocol and a burst control state machine. The burst control state machine is adapted to receive BPDUs and, under certain conditions, delay responding with its own BPDU falsely advertising itself as the new root bridge. The delay is preferably long enough to enable another bridge to identity the true root bridge. The delay, e.g., a burst control delay, is preferably equal to or less than a Hello time timer value generally defined to be 2 seconds in a Rapid Spanning Tree Protocol standard, for example.
