Port Link Aggregation
The GS adheres to the IEEE 802.3ad standard for static and dynamic port link aggregation.
Bandwidth Control
You can set the amount of bandwidth that an individual port can use. The switch allows you to define a maximum
allowable bandwidth for incoming and/or out-going traffic on a port.
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.
Broadcast storm control.
Quality of Service
Eight priority queues so you can ensure mission-critical data gets delivered on time.
Follows the IEEE 802.1p priority setting.
Advanced policy-based traffic shaping.
STP (Spanning Tree Protocol) / RSTP (Rapid STP)
(R)STP detects and breaks network loops and provides backup links between switches, bridges or routers. It allows
a switch to interact with other (R)STP -compliant switches in your network to ensure that only one path exists
between any two stations on the network.
Cluster Management
Cluster Management allows you to manage switches through one switch, called the cluster manager. The switches
must be directly connected and be in the same VLAN group so as to be able to communicate with one another.

1.3 Applications

This section shows a few examples of using the switch in various network environments.
1.3.1 Backbone Application
In this application, the switch is an ideal solution for small networks where rapid growth can be expected in the
near future.
The switch can be used standalone for a group of heavy traffic users. You can connect computers directly to the
switch's ports or connect other switches to the GS.
In this example, all computers connected directly or indirectly to the GS can share super high-speed applications on
the Gigabit server.
To expand the network, simply add more networking devices such as switches, routers, firewalls, print servers etc.
