  2. Ethernet Configuration Testing Protocol - Wikipedia

    en.wikipedia.org/wiki/Ethernet_Configuration...

    Ethernet Configuration Testing Protocol is a diagnostic protocol included in the Xerox Ethernet II specification. [1] Functionality of the protocol is similar to that offered by ping but it operates at the data link layer as opposed to the network layer. Ethernet Configuration Testing Protocol was implemented on DEC hosts and Cisco routers. [2]

  3. Loopback - Wikipedia

    en.wikipedia.org/wiki/Loopback

    This is called a loopback test and can be performed within a modem or transceiver by connecting its output to its own input. A circuit between two points in different locations may be tested by applying a test signal on the circuit in one location, and having the network device at the other location send a signal back through the circuit.

  4. IEEE 802.1ag - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.1ag

    IEEE 802.1ag is an amendment to the IEEE 802.1Q networking standard which introduces Connectivity Fault Management (CFM).This defines protocols and practices for the operations, administration, and maintenance (OAM) of paths through 802.1 bridges and local area networks (LANs).

  5. IEEE 802.3 - Wikipedia

    en.wikipedia.org/wiki/IEEE_802.3

    IEEE 802.3 is a working group and a collection of standards defining the physical layer and data link layer's media access control (MAC) of wired Ethernet.The standards are produced by the working group of the Institute of Electrical and Electronics Engineers (IEEE).

  6. Network tap - Wikipedia

    en.wikipedia.org/wiki/Network_tap

    A network tap is a system that monitors events on a local network. A tap is typically a dedicated hardware device, which provides a way to access the data flowing across a computer network. The network tap has (at least) three ports: an A port, a B port, and a monitor port. A tap inserted between A and B passes all traffic (send and receive ...

  7. Protocol analyzer - Wikipedia

    en.wikipedia.org/wiki/Protocol_analyzer

    A protocol analyzer is a tool (hardware or software) used to capture and analyze signals and data traffic over a communication channel.Such a channel varies from a local computer bus to a satellite link, that provides a means of communication using a standard communication protocol (networked or point-to-point).

  8. LAN eXtensions for Instrumentation - Wikipedia

    en.wikipedia.org/wiki/LAN_eXtensions_for...

    Proposed in 2005 by Keysight [2] and VTI Instruments, [3] the LXI standard adapts the Ethernet and World Wide Web standards to test and measurement applications. [4] The standard defines how existing standards should be used in instrumentation applications to provide a consistent feel and ensure compatibility between equipment.

  9. JTAG - Wikipedia

    en.wikipedia.org/wiki/JTAG

    JTAG (named after the Joint Test Action Group which codified it) is an industry standard for verifying designs of and testing printed circuit boards after manufacture.. JTAG implements standards for on-chip instrumentation in electronic design automation (EDA) as a complementary tool to digital simulation. [1]
