(IGMP) options for multimedia applications, such as desktop video
conferencing, that use IP multicast addresses.
Configure permanent MAC addresses: Allows permanent mapping
between a network device and a port.
Configure port security: Configures the switch to only allow the
transmission of authorized traffic over a particular port(s).
Configure MAC address filtering: Allows the switch to drop traffic
based on MAC source or destination addresses.
Configure Ethernet multicast filtering: Blocks or forwards traffic over
each port for Ethernet (MAC-based) multicast groups.
