24 + 4 SFP Module Slots Gigabit Web Smart Switch
Gigabit Ethernet Switches
The Switch is a cost-effective web smart switch that meets all IEEE 802.3/u/x/z Gigabit, Fast Ethernet specifications. It is equipped with 20 ports 10/100/1000Base-TP and 4 dual media ports of optional 10/100/1000Base-T or SFP modules. The switch can be managed through Ethernet port using Web browser, the administrator can log in the switch through network to monitor, configure and control activity of each port. In addition, the switch implements the QoS (Quality of Service), Port Mirror, VLAN, LACP, LAN security, Multicasting video stream protocol, and SNMP v2c. It is suitable for SMB application.
QoS with Four Priority Queues
The QoS(Quality Of Service) feature provides four internal queues to support four different classifications of traffic. High priority packet streams experience less delay inside the switch, which supports lower latency for certain delay-sensitive traffic. The swith classify the packet as one of the four priorities according to 802.1p priority tag, DiffServ and/or IP TOS. The QoS operate at full wire speed. The actual scheduling at each egress port can be based upon a strict priority, weighted round robin or a mix of both.
Multicasting VLAN reduce the multicast video streaming traffic in DVB application
Multicast VLAN is designed for applications (such as Digital Video Broadcasting (DVB)) using multicast traffic across an IP Ethernet network. The feature allows one single multicast VLAN to be shared among different subscriber VLANs on the network. This improves bandwidth utilization by reducing multicast traffic in the subscriber VLANs and simplifies multicast group management.
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.
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.
