VLAN A VLAN (Virtual Local Area Network) allows a physical network to be
partitioned into multiple logical networks. Devices on a logical network
belong to one group. A device can belong to more than one group. With
VLAN, a device cannot directly talk to or hear from devices that are not in
the same group(s); the traffic must first go through a router.
MAC Address Filter Filter traffic based on the source and/or destination MAC address and
VLAN group (ID).
DHCP Client DHCP (Dynamic Host Configuration Protocol RFC 2131 and RFC 2132)
allows individual computers to obtain TCP/IP configuration at start-up
from a server. You can configure the Switch as a DHCP client to obtain
TCP/IP information (such as the IP address and subnet mask) from a
DHCP server. If you disable the DHCP service, you must manually enter
the TCP/IP information.
DHCP Relay Use this feature to have the relay DHCP requests to DHCP servers on
your network.
IGMP Snooping The Switch supports IGMP snooping enabling group multicast traffic to
be only forwarded to ports that are members of that group; thus allowing
you to significantly reduce multicast traffic passing through your Switch.
