Abstract
A system and method is provided for prioritizing packets at an Ethernet interface of a network device based on the destination MAC address in the packets. The Ethernet interface has a MAC table that lists the MAC addresses that can be accepted by the Ethernet interface. The MAC table can include one or more MAC addresses associated with low priority packets and one or more MAC addresses associated with high priority packets. When conditions at the network device exceed a threshold, the MAC table can be updated to disable or delete the MAC addresses associated with the low priority packets. By disabling the MAC addresses for low priority packets, only the MAC addresses associated with high priority packets remain in the MAC table, thereby enabling only high priority packets to be recognized and passed by the Ethernet interface to the CPU.
