A switch is a device used in computer networks that connects other devices together. • Multiple data cables are plugged into a switch to enable communication between different networked devices. • Switches manage the flow of data across a network by transmitting the received network packet to the one or more intended recipient devices. • Each networked device connected to a switch can be identified by its network address, thus the switch identifies the exact recipient and directs the data to the intended recipient only. • Switches are broadly classified in two categories : • Managed Switches and Unmanaged Switches • Unmanaged Switches – • 1. They are basic plug-and-play switches. They come with a fixed configuration and do not allow any change to this configuration. • 2. They don’t have any remote configuration, management, or monitoring options. But many unmanaged switches could be locally monitored and configured via LED indicators and DIP switches • Managed Switches – • 1. All the features of an unmanaged switch are present in a managed switch. • 2. They could be configured, managed and monitored even remotely. • 3. They use SNMP (Simple Network Management Protocol) for monitoring the health of the network and connected devices on the network. • 4. They are costlier than the Unmanaged Switches • Few Additional Advantages of Managed Switches over Unmanaged are • A. Quality of Service – Managed switches allow to prioritize network traffic by assigning a higher priority to critical traffic. This way critical data transmission is ensured in heavy traffic times also. • B. VLAN – VLAN (Virtual LAN) allow a switch to logically group devices together to isolate traffic between these groups even when the traffic is passing over the same physical switch. Like the Finance department computers could be grouped in a separate VLAN so that their data does not gets affected due to the data of other departments like Marketing , Commercials etc. This way an additional level of security is also added as critical data gets separated toa different network (VLAN). • C. Redundancy – Managed switches support redundancy and are useful in case a link or data path gets broken. An alternate data path is provided by the Managed Switch for traffic. (This is useful only when the two network devices are having multiple paths between them) • D. Port Mirroring – By this feature any port traffic could be forwarded to a monitor port without disturbing the traffic on the source port. This way without disturbing the switch and other connected devices we can monitor each and every port on the monitor port. • • Do Subscribe Eclectic Classes. • Please press the Like Button if you like the video. • Do Provide your feedback in the Comment section. • #EthernetSwitch, #ManagedSwitch, #PLC, #Switch, #Instrumentation, #NetworkSwitch
