Abstract

See full text

A network device includes a plurality of ports and at least one packet processor separate from a central processing unit (CPU). The packet processor is configured to forward a received packet based on a look-up of a destination address of the received packet in a table of learned entries that associate first addresses checked by the CPU to the ports of the network device, to add a new provisional entry that associates a source address with an ingress port of the received packet based on a look-up of the source address in both the learned entries and provisional entries that associate second addresses to be checked by the CPU to the ports of the network device, and to upgrade the new provisional entry to a learned entry with a delay time (e.g., a pre-determined time period) to allow the CPU to check the source address.
