  2. 2.5GBASE-T and 5GBASE-T - Wikipedia

    en.wikipedia.org/wiki/2.5GBASE-T_and_5GBASE-T

    The IEEE 802.3ch-2020 2.5GBASE-T1, 5GBASE-T1, and 10GBASE-T1 standards are derived from the IEEE 802.3bp-2016 1000BASE-T1 Ethernet over single twisted pair standard, and share very little in common with the similarly named 2.5GBASE-T and 5GBASE-T standards at the PHY layer. 2.5GBASE-T1, 5GBASE-T1, and 10GBASE-T1 can run over a single twisted ...

  3. Duplex mismatch - Wikipedia

    en.wikipedia.org/wiki/Duplex_mismatch

    Single packets are sent and acknowledged without problems. As a result, a simple ping command fails to detect a duplex mismatch because single packets and their resulting acknowledgments at 1-second intervals do not cause any problem on the network. A terminal session which sends data slowly (in very short bursts) can also communicate successfully.

    2. Check the physical connection - A loose cable or cord can often be the cause of a connection problem. Make sure everything is securely connected to the wall and device. 3. Reboot your modem/router - Sometimes the old "turn it off and on again" approach actually does work! Just wait about five minutes before turning it back on to make sure ...

  5. Autonegotiation - Wikipedia

    en.wikipedia.org/wiki/Autonegotiation

    The first version of the autonegotiation specification, in the 1995 IEEE 802.3u Fast Ethernet standard, was implemented differently by different manufacturers leading to interoperability issues. These problems led many network administrators to manually set the speed and duplex mode of each network interface.

  6. Realtek Remote Control Protocol - Wikipedia

    en.wikipedia.org/wiki/Realtek_Remote_Control...

    The Realtek Remote Control Protocol (RRCP), developed by Realtek, is an application layer protocol, running directly over Ethernet frames. The main idea behind this protocol is to allow direct access to the internal register of an Ethernet switch controller (ASIC) over an Ethernet network itself.

  7. Realtek - Wikipedia

    en.wikipedia.org/wiki/Realtek

    Realtek was founded in October 1987 and subsequently listed on the Taiwan Stock Exchange in 1998. Realtek has manufactured and sold a variety of microchips globally. Its product lines broadly fall into three categories: communications network ICs, computer peripheral ICs, and multimedia ICs.

  8. Route flapping - Wikipedia

    en.wikipedia.org/wiki/Route_flapping

    In both cases, it prevents the network from converging. Route flapping can be contained to a smaller area of the network if route aggregation is used. As an aggregate route will not be withdrawn as long as at least one of the aggregated subnets is still valid, a flapping route that is part of an aggregate will not disturb the routers that ...

  9. Ethernet physical layer - Wikipedia

    en.wikipedia.org/wiki/Ethernet_physical_layer

    The original 2.94 Mbit/s Ethernet implementation had eight-bit addresses and other differences in frame format. [9] 10BASE5: 802.3-1985 (8) AUI, N, vampire tap: 500 m RG-8/U Original standard uses a single coaxial cable in which a connection is made by tapping into the single cable, drilling in to make contact with the core and the screen.
