  • What is a normal network speed for a fiber optic switch

    What is a normal network speed for a fiber optic switch

    Quick answer: fiber optic networks commonly run at 1G, 10G, 25G, 40G, 100G, 200G, 400G and 800G, while carrier and backbone systems can scale much higher with WDM. In real installations, the speed is set by the switch port, transceiver or cable assembly, modulation, fiber type, connector, link. Network switches are hardware in current-day network architectures, and hence, they are used to create or control traffic in a local area network (LAN) by dividing it into different segments.

  • Access Switch Loop Prevention

    Access Switch Loop Prevention

    STP prevents loops by blocking redundant paths, but misconfigurations or STP timer changes can cause loops to reform unexpectedly. Our existing design is quite simple, it consists of several switches acting as layer 2 (around 6-7) and all of them are connected to a switch through single interface trunk ports. This switch is connected to a firewall which is the gateway for all VLANS defined, which are extended in all the. The loop prevention feature of most switches is "Rapid Spanning Tree Protocol" or RSTP. It's normally impossible to get a bridging loop without another switch at the end. I have recently been told by a consultant that access layer loops can be prevented without spanning tree on host ports by using Layer 3 routing.
