flooding port
Use this command to enhance security and privacy and to improve network performance by disabling
Layer 2, or egress, flooding on some packets. This is particularly useful when you are working on an
edge device in the network. Limiting flooded egress packets to selected interfaces is also known as
upstream forwarding
NOTE
Disabling egress flooding with static MAC addresses can affect many protocols, such as IP and ARP among others.
