Section 10. Defining the Forwarding Database
Packets addressed to destinations stored in either the Static or Dynamic databases are immediately forwarded to
the port. The Dynamic MAC Address Table can be sorted by interface, VLAN, or MAC Address, whereas MAC
addresses are dynamically learned as packets from sources that arrive at the device. Static addresses are config-
ured manually.
An address becomes associated with a port by learning the port from the frame's source address, but if a frame
that is addressed to a destination MAC address is not associated with a port, that frame is flooded to all relevant
VLAN ports. To prevent the bridging table from overflowing, a dynamic MAC address, from which no traffic arrives
for a set period, is erased.
This section contains information for defining both static and dynamic forwarding database entries, and includes
the following topics:
•
Defining Static Forwarding Database Entries
•
