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.
