Abstract
A network switch configured for switching data packets across multiple ports and for supporting trunked data paths uses an address table to generate frame forwarding information. When a link in a trunked data path experiences a change in its operating status, the trunk data path is reconfigured to reflect the current operating conditions, without reprogramming the address table or powering down the switch.
