Re: manual sticky mac address

As entering manual addresses is an extremely difficult and time consuming
task. Making every port sticky saved you looking up and typing in all the
addresses. When using sticky, the switch learns all the MAC addresses
dynamically and all you need to do is typing: write. Saves a lot of work :-)
