  2. Limit switch - Wikipedia

    en.wikipedia.org/wiki/Limit_switch

    A limit switch with a roller-lever operator; this is installed on a gate on a canal lock, and indicates the position of a gate to a control system A limit switch mounted on a moving part of a bridge In electrical engineering , a limit switch is a switch operated by the motion of a machine part or the presence of an object.

  3. Ethernet flow control - Wikipedia

    en.wikipedia.org/wiki/Ethernet_flow_control

    A more likely scenario is network congestion within a switch. For example, a flow can come into a switch on a higher speed link than the one it goes out, or several flows can come in over two or more links that total more than an output link's bandwidth. These will eventually exhaust any amount of buffering in the switch.

  4. Spanning Tree Protocol - Wikipedia

    en.wikipedia.org/wiki/Spanning_Tree_Protocol

    The switch with the lowest priority of all the switches will be the root; if there is a tie, then the switch with the lowest priority and lowest MAC address will be the root. For example, if switches A (MAC = 0200.0000.1111 ) and B (MAC = 0200.0000.2222 ) both have a priority of 32,768 then switch A will be selected as the root bridge.

  5. Autonegotiation - Wikipedia

    en.wikipedia.org/wiki/Autonegotiation

    Autonegotiation is a signaling mechanism and procedure used by Ethernet over twisted pair by which two connected devices choose common transmission parameters, such as speed, duplex mode, and flow control.

  6. Forwarding information base - Wikipedia

    en.wikipedia.org/wiki/Forwarding_information_base

    The role of an Ethernet switch is to forward Ethernet frames from one port to another. The presence of a FIB is one attribute that separates a switch from a hub. Without a functional FIB, all frames received by a network switch would be echoed back out to all other ports, much like an Ethernet hub.

  7. Ethernet Ring Protection Switching - Wikipedia

    en.wikipedia.org/wiki/Ethernet_Ring_Protection...

    Ethernet Ring Protection Switching (ERPS) is an effort at ITU-T under G.8032 Recommendation to provide sub-50ms protection and recovery switching for Ethernet traffic in a ring topology and at the same time ensuring that there are no loops formed at the Ethernet layer.

  8. IGMP snooping - Wikipedia

    en.wikipedia.org/wiki/IGMP_snooping

    The switch is trying to ensure the router only has a single report for the group, regardless of how many active listeners there are. If there are two active listeners in a group and the first one leaves, then the switch determines that the router does not need this information since it does not affect the status of the group from the router's ...

  9. Data monitoring switch - Wikipedia

    en.wikipedia.org/wiki/Data_monitoring_switch

    Data monitoring switches support either or both of the following internal management interfaces: A text-based command-line interface (CLI) accessed with a terminal emulation program either locally over a serial port or remotely over a secure (e.g., SSH) network connection; this interface is sometimes preferred by network administrators, although many data center professionals complain that CLI ...
