Types of MAC address entries

A MAC address table can contain the following types of entries:

•Static entries—Manually added and never age out.

•Dynamic entries—Manually added or dynamically learned, and might age out.

•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.
