Abstract
A network switch may include ports at which network packets are received from a network. The switch may maintain a packet forwarding database having forwarding database entries that are each associated with a corresponding port. The switch may perform flushing operations to delete forwarding database entries that are associated with a selected port or a selected group of ports. The flushing operations may be performed by modifying an aging table that is maintained by the switch. The aging table may include entries that each identifies an aging threshold value and at least one port of the switch. Flushing operations for a selected port may be performed by setting the aging threshold value to zero for an aging table entry that correspond to the selected port so that forwarding table entries associated with the selected port are deleted during a subsequent aging process.
