Types of forwarding database entries

The forwarding database can contain the following types of entries:
Dynamic—A dynamic entry is a temporary entry that remains in the database only until the entry is no longer used.
By default, a dynamic entry ages out if it remains unused for 300 seconds (5 minutes). All dynamic entries are
removed if the WSS is powered down or rebooted.
Static—A static entry does not age out, regardless of how often the entry is used. However, like dynamic entries,
static entries are removed if the WSS is powered down or rebooted.
Permanent—A permanent entry does not age out, regardless of how often the entry is used. In addition, a permanent
entry remains in the forwarding database even following a reboot or power cycle.
