Benefits
PoE Save Your Power Infrastructure Cost

12-PoE ports allow power to be supplied to end devices, such as Wireless Access Points or VoIP Phones, directly through the existing LAN cables. By supplying the power mid-span, you can centralize power distribution and backup without the need to increase infrastructure.

2 Dual Media for Flexible Fiber Connection

11, 12 dual media port 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.

QoS support layer 4 classification

The switch supports not only Layer 2 802.1p Priority Queue control, but also supports programmable higher layer classification and prioritization to enable enhanced Quality of Service (Qos) support for real time applications base on information taken from Layer 2 to Layer 4, such as VoIP.

Q-in-Q VLAN for performance & security

The VLAN feature in the switch offers the benefits of both security and performance. VLAN is used to isolate traffic between different users and thus provides better security. Limiting the broadcast traffic to within the same VLAN broadcast domain also enhances performance. VLAN support enabling advanced techniques such as "802.1Q-in-1Q" to be deployed.

802.3ad Port Trunk for Bandwidth Aggregation

The Gigabit ports can be combined together to create a multi-link load- sharing trunk. Up to 6 Gigabit ports can be set up per trunk for bandwidth up to 12Gbps, all traffic is aggregated based on MAC addresses, thus balancing the traffic load. The switch supports up to 6 trunking groups. Port trunks are useful for switch-to-switch cascading, providing very high full-duplex speeds.

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.

802.1D Compatible & 802.1w Rapid Spanning Tree

For mission critical environments with multiple switches supporting STP, you can configure the switches with a redundant backup bridge path, so transmission and reception of packets can be guaranteed in event of any fail- over switch on the network.

Broadcast/Multicast Storm Control

To limit too many broadcast/multicast flooding in the network, broadcast/ multicast storm control is used to restrict excess traffic. Threshold values are available to control the rate limit for each port. Packets are discarded if the count exceeds the configured upper threshold.
