The MAC address table on a Cisco Nexus Server switch is full .What Layer 2 network behavior will occur while the network MAC address table remains full?

Not all frames are flooded - only frames with destination MACs missing from the table are flooded; frames matching existing table entries are still unicast forwarded to their learned ports.

A full CAM table prevents new MAC address learning, causing frames with unknown destination addresses to be treated as unknown unicast and flooded out all ports except the ingress port. Frames whose destination MAC already exists in the table continue to be forwarded normally to the correct port.

Cisco switches do not automatically reset or clear the entire MAC address table when it reaches capacity; that would cause a severe disruption and is not standard behavior.

The switch does not proactively remove all dynamically learned addresses when the table is full; existing entries expire only when their aging timer (default 300 seconds) elapses.
