Configurable on the Switch
4 management accounts configured on the Switch.
Authentication via RADIUS and also available.
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)
Relay
Use this feature to have the Switch forward 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.
Classifier and Policy You can create a policy to define actions to be performed on a traffic flow
grouped by a classifier according to specific criteria such as the IP
address, port number or protocol type, etc.
Queuing Queuing is used to help solve performance degradation when there is
network congestion. The following 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.
Bandwidth Control Bandwidth control means defining a maximum allowable bandwidth for
incoming and/or out-going traffic flows on a port.
Broadcast Storm Control Broadcast storm control limits the number of broadcast, multicast and
destination lookup failure (DLF) packets the Switch receives per second
on the ports.
