How entries enter the forwarding database

An entry enters the forwarding database in one of the following ways:
Learned from traffic received by the WSS —When the WSS receives a packet, the switch adds the
packet’s source MAC address to the forwarding database if the database does not already contain an entry
for that MAC address.
Added by the system administrator—You can add static and permanent unicast entries to the forwarding
database. (You cannot add a multicast or broadcast address as a permanent or static forwarding database
entry.)
Added by the WSS itself—For example, the authentication protocols can add entries for wired and
wireless authentication users. The WSS also adds any static entries added by the system administrator and
saved in the configuration file.
