Key Features
Type: Hubs: The term hub is applicable to a wide range of devices: some can not be used on Ethernet networks, others are Ethernet hubs. In the case of a network of small size, the choice of a hub is often limited to search for the best price and predict the evolution of your network. Switches: These devices filter and transfer data packets from one LAN segment to another. KVM switches (keyboard, video, mouse) to control multiple computers. They are very popular with users who have upgraded their computer systems and staff who wish to continue using their old computer without having to buy another keyboard, another screen or another Ethernet souris.Commutateur
OSI Layer: Switches Level 2 (data link level)
Layer 2 switches operate on the basis of physical network addresses. These addresses, also known as link-level addresses, physical or MAC, are used to identify each device. Most devices are a permanent physical address during the manufacturing process.
Layer 2 switches are fast because they simply sorting physical addresses, without trying to learnmore about the destination of data packets.
Switches Layer 3 (network layer)
The Layer 3 switches use network or IP addresses that identify locations on the network. Unlike Layer 2 switches, they carefully examine the network addresses to identify network locations as well as the physical device. Placement is defined as a LAN workstation, a computer memory location or a different data packet transmitted over a network.
Switches that operate at level 3 are systems that include intelligent routing functions for actively calculate the best way to send a packet to its destination. Despite their "intelligence", they are sometimes slower than switches level 2, especially when their algoritlmes, their matrix or processor does not support the high débits.Niveau 2
System manageable: Manageable
Manageable device includes management features, configuration and monitoring that control and manage the network through various status indicators.
Unmanageable
Unmanaged device can not be configured or managed over a network. You do not need to set parameters or configure the périphérique.Gérable

Additional Ports: 2 x SFP
Performance
MAC address entries: 8000
VLAN: All switches do not support the same number of VLANs.
VLAN (or VLAN) is a local area network designed to combine workstations based on criteria other than simple geography. It can, for example, to make associations with service, user type or main application. The virtual LAN controller can change or add workstations and manage load balancing and bandwidth allocation more easily than can a simple physical picture of the LAN.
The VLAN corresponds to a switch function capable of sharing the network into several parts. It is used for security reasons and (in the case of larger networks) to more easily move computers and services. VLAN allows a particular change only the switch instead to reconfigure computers séparément.64 20

Standards and Protocols
LAN standards: These standards of connection supported by the device. Remember to make sure they are compatible with the devices you want connecter.IEEE 802.1p LAN Layer 2 (QoS / CoS Protocol for Traffic Prioritization)
IEEE802.1Q (VLAN)
IEEE 802.3 CSMA / CD or Ethernet
IEEE 802.3u 100 Mbps (Fast Ethernet)
IEEE 802.3ab 1000 Mbps (Gigabit Ethernet)
IEEE 802.3x (flow control)
IEEE 802.1x (Port Access Control for WLANs)
Switching Method / transfer: Store-and-forward
Management protocols: For management protocols means the protocols that the device uses to perform management operations, configuration and surveillance.HTTP
Protocols: The protocols indicate the signals that the switch or hub connected to the device will take over. They define the syntax (arrangements, formats and patterns of bits and bytes) and semantics (system control, information context or meaning of patterns of bits and bytes) of data exchanged, as well as other parameters such the timing and flow of données.ACL
