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.

Layer 2 Management Forward traffic based on the destination MAC address and VLAN group

(ID).

QoS Queuing is used to help solve performance degradation when there is

network congestion. Two scheduling services are supported: Strict

Priority (SP) 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.

Rate Control Rate control is a combination of bandwidth management and broadcast

storm control. This feature allows you to set limits for incoming and

outgoing traffic on the ports. The broadcast storm control feature helps

prevent broadcast, multicast or unknown unicast traffic from flooding

your network.

Port Mirroring Port mirroring allows you to copy traffic going from one or all ports to

another or all ports in order that you can examine the traffic from the

mirror port (the port you copy the traffic to) without interference.

Link Aggregation Link aggregation (trunking) is the grouping of physical ports into one

logical higher-capacity link. You may want to trunk ports if for example, it

is cheaper to use multiple lower-speed links than to under-utilize a high-

speed, but more costly, single-port link.

Device Management Use the web configurator to easily configure the rich range of features on

the Switch.
