802.1x Access Control Improve Network Security
802.1x features enable user authentication for each network access attempt. Port security
features allow you to limit the number of MAC addresses per port in order to control the
number of stations for each port. Static MAC addresses can be defined for each port to ensure
only registered machines are allowed to access. By enabling both of these features, you can
establish an access mechanism based on user and machine identities, as well as control the
number of access stations.
Port Trunk for Bandwidth Aggregation
The Gigabit ports can be combined together to create a multi-link load-sharing trunk. Up to 8
Gigabit ports can be set up per trunk. The switch supports up to 8 trunking groups. Port trunks
are useful for switch-to-switch cascading, providing very high full-duplex speeds.
Trap Event for Exception Management
We use SNMP Trap mechanism to inform supervisor to know the instant abnormal status of
the switch.
4 Dual Media Ports for Flexible Fiber Connection
Four dual media ports are provided for flexible fiber connection. You can select to install
optional transceiver modules in these slots for short, medium or long distance fiber backbone
attachment. Use of the SFP will disable their corresponding built-in 10/100/1000Base-T
connections.
Build-in Web-base Management
Instead of using CLI interface, we provide a more convenient GUI for user. We just need to
configure switch via Web Browser. It is more quickly for user to familiar the method to control
switch on the basis of this design.
