Defining Dynamic and Static MAC Addresses

Packets addressed to destinations stored in either the Static or Dynamic databases are immediately forwarded to the port.
The MAC Address Table Page 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 configured manually.
An address becomes associated with a port by learning the port from the frame's source address, however if a frame
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.
To prevent static MAC addresses from being deleted when the device is reset, ensure that the port attached to the MAC
address is locked.
