The latest Layer 2 Managed Switch from LevelOne is a perfect solution for young and dynamic Offices with small network user groups. The GSW-0890 provides Gigabit and Fiber Optic connection possibilities that enable a high-speed networking environment with long range connectivity to remote located networks. It supports SNMP, Web UI and CLI management interfaces and is equipped with 8 Gigabit TP ports of which 2 are dual media ports that can accommodate optional 10/100/1000Base-T or SFP modules. The GSW-0890 further implements QoS (Quality of Service), Mac Filtering Policy, Port Mirror, VLAN and full Layer 2 protocol.

Dual Media Port Support
The GSW-0890 provides shared dual media port support on ports 7 and 8 for more flexible fiber connectivity. SFP transceiver modules can be connected to provide short, medium and long distance fiber backbone capability.

QoS with Layer 4 Classification Support
The switch provides support for Layer 2 802.11p Priority Queue control as well as programmable higher layer classification and prioritization to enable enhanced Quality of Service (QoS) support for real time applications based on information taken from Layer 2 to 4, such as VoIP and Real-time video streaming applications.

Network Management Features for Comprehensive Network Control
The GSW-0890 8-port Layer 2 switch incorporates Port Mirroring, Q-in-Q VLAN, Access Control and Port Trunking among its network management features. Port mirroring copies traffic from a specific port to a target port. This mechanism helps track network errors or abnormal packet transmission without interrupting the flow of data.

The VLAN feature in the switch offers the benefits of both security and performance. VLAN is applied 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. Q-in-Q, the use of double VLAN tags, is an efficient method for enabling Subscriber Aggregation.

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.

The GSW-0890 is also 802.3ad Port Trunk compliant. The Gigabit ports can be combined together to create a multi-link load-sharing trunk. Up to 4 Gigabit ports can be set up per trunk for bandwidth up to 8Gbps, all traffic is aggregated based on MAC addresses, thus balancing the traffic load. The switch supports up to 4 trunking groups. Port trunks are useful for switch-to-switch cascading, providing very high full-duplex speeds

802.1D & 802.1w Rapid Spanning Tree Compatible
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 the event of any switch failure 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.
