Table 101 Feature Descriptions
FEATURE DESCRIPTION
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 (Dynamic Host
Configuration Protocol)
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.
Differentiated Services
(DiffServ)
With DiffServ, the Switch marks packets so that they receive
specific per-hop treatment at DiffServ-compliant network
devices along the route based on the application types and
traffic flow.
Queuing Queuing is used to help solve performance degradation when
there is network congestion. Three scheduling services are
supported: Strict Priority Queuing (SPQ) and Weighted Round
Robin (WRR). This allows the Switch to maintain separate
queues for packets from each individual source or flow and
prevent a source from monopolizing the bandwidth.
