Product Introduction Product Introduction Network Switch A switch connects to devices (computers, access points, cameras, VoIP phones, NAS, servers, etc. — or other switches) via Ethernet cables to establish a network or to expand a network. Product Introduction Smart Network Switch Smart switches have capabilities that lie between unmanaged and managed switches and normally provide the configuration of basic settings. Product Introduction Manageability — typically provided using a Web Interface which allows performance monitoring (port activity), the ability to configure network trunks (bandwidth control), and supports Port Mirroring. QoS (Quality of Service) — which prioritizes network traffic to support delay sensitive applications such as VoIP (Voice over Internet Protocol) and Streaming Video and enhanced security which offers support for VLANs (Virtual LANs). Product Introduction Smart Network Switch Like a bridge, a Layer 2 switch connects segments of a network and makes filtering decisions about which data is allowed to travel between the segments and which data stays on a single segment. But while a bridge may connect only two segments, a Layer 2 switch can connect many segments. Product Introduction Basically a layer 2 switch operates utilizing Mac addresses in it's caching table to quickly pass information from port to port. A layer 2 switch is essentially a multiport transparent bridge. A layer 2 switch will learn about MAC addresses connected to each port and passes frames marked for those ports. It also knows that if a frame is sent out a port but is looking for the MAC address of the port it is connected to and drop that frame. Layer 2 switches use the MAC address of data packets to determine where those packets should go. When you connect a Layer 2 switch to a network, it immediately “listens” for all the devices on all the segments that are connected to the switch's ports. Product Introduction It learns the MAC addresses of all of those devices and creates a segment table or forwarding table. Because a switch can discover all this for itself, it is relatively easy to connect a switch to a network. This self-learning ability is one of the important features of Layer 2 switches. The IEEE 802.1D standard defines this bridge and switching function. Product Introduction Power over Ethernet (PoE) A PoE device can send or receive power via Ethernet, but not send and receive power at the same time. The maximum cable length recommended were up to 100 meters. The sender is a Power Sourcing device (PSE) like a PoE switch, while a device (like an access point, IP Camera or VoIP phone) that is powered via PoE is a Powered Device (PD). The PSE supplies power, which can be divided between several PDs. Product Introduction Product Introduction IEEE Standard Power Classes Product Introduction Standard PoE Parameters and Comparison Notes : 1. Most Switched power supplies within the devices will lose up to 10 to 20% of the available power. 2. Most cable specification allow assumption of more current carrying capacity and lower resistance (20 Ohms for Cat 3 vs Cat 5) 3. The standard of IEEE 802.3at and IEEE 802.3af is classified Class 4. 4. All our Indoor AP is Class, mode B, End-Span. Product Introduction Standard PoE Current flow The powered device completes the current loop. DC current within specific minimum and maximum thresholds means that a PoE-powered device is connected and requires continued PoE Product Introduction Standard PoE flow chart The flow chart is a guide that PoE support different types of hardware.

WEB Interface System PoE Management It is capable of delivering up to 15.4W of power to devices such as wireless access points, IP phones and IP Cameras, provide flexibility and ease of deployment to your network. To help you better control and monitor your power resource. It will show the total power consumption of the device connected. WEB Interface Web Interfaces System PoE Port Configuration In Port Configuration, you can configure and view the operation mode for each port. If priority is set all “low”, it will auto allocate power resource. WEB Interface Web Interfaces L2 Feature Port Trunking In Computer Networking, Port Trunking refers to the use of multiple network connections in parallel to increase the link speed beyond the limits of any one single cable or port. This is called link aggregation. These aggregated links may be used to interconnect switches or to connect high-capacity servers to a network. WEB Interface Web Interfaces L2 Feature Port Trunking Topology •Port Trunking need to enable in both switches. •Trunks carry traffic from all VLANs to and from the switch by default but can be configured to carry only specified VLAN traffic. Port Trunking WEB Interface Web Interfaces L2 Feature IGMP Snooping IGMP snooping is the process of listening to Internet Group Management Protocol (IGMP) network traffic. The feature allows a network switch to listen in on the IGMP conversation between hosts and routers. By listening to these conversations the switch maintains a map of which links need which IP multicast streams. Multicasts may be filtered from the links which do not need them and thus controls which ports receive specific multicast traffic. WEB Interface Web Interfaces L2 Feature Port Mirroring Port mirroring is used on a network switch to send a copy of network packets seen on one switch port (or an entire VLAN) to a network monitoring connection on another switch port. This is commonly used for network appliances that require monitoring of network traffic WEB Interface VLAN – Virtual LAN PVID (Port VLAN ID) A Port VLAN ID (pvid) is a default VLAN ID that is assigned to an access port to designate the virtual LAN segment to which this port is connected. WEB Interface Web Interfaces VLAN – Virtual LAN 802.1Q – VLAN Tagging 802.1Q allow the user to configure the network port to be tag or untag to the VID. Port 1 configure VID10 and VID20 SSID 1 tag VID10 SSID 2 tag VID10 WEB Interface VLAN – Virtual LAN Port-based VLAN To provide priority to identified network traffic including dedicated bandwidth, controlled jitter and latency that is required by real time applications while improving quality by reducing packet loss. WEB Interface QoS – Quality of Service Cos (Class of Services) Priority queuing ensures high-priority traffic gets delivered efficiently, even during congestion from high-traffic bursts. For example, certain types of traffic that require minimal delay, such as Voice, Video, and real-time traffic can be assigned to a high priority queue, while other traffic can be assigned to a lower priority queue. WEB Interface QoS – Quality of Service Storm Control Storm control prevents traffic on a LAN from being disrupted by a broadcast, multicast, or unicast storm on a port. This occupies bandwidth and loads all nodes on all ports. WEB Interface QoS – Quality of Service Bandwidth Control To provide priority to identified network traffic including dedicated bandwidth, controlled jitter and latency that is required by real time applications while improving quality by reducing packet loss.
