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.
