Blackhole entries
—Manually configured and never age out. They are configured for filtering
out frames with specific source or destination MAC addresses. For example, to block all frames
destined for a specific user for security concerns, you can configure the MAC address of this
user as a blackhole MAC address entry.
A static or blackhole MAC address entry can overwrite a dynamic MAC address entry, but not vice
versa.
