This was in my Cisco training. Unidirectional line break.

No. I don’t speak Japanese. Or whatever that is.

    x is bad

    Sounds like you got the gist.

    Just wait for later in the training. You’ll beg for japanese instead.

      Thanks! I’m about 2/3 the way through my CCNA. Just passed the CCST Network and Cybersecurity. Finished something called Cisco Meraki Engineer or some such shit today. I’m considering doing testing for Cisco Meraki Solutions Specialist later, as it appears I’ve covered all those topics, but the CCNA is my real goal. Mostly, I need to learn mgt protocols now, OSPF and BGP. I’m workin my ass off.

      Ya it came from an exercise about STP Loop Guard. Cool.

        Plugging in a VOIP phone to the same switch with both interfaces will have a similar effect if loopguard is not enabled.

          I will try that! Actually, I’ve accidentally done that shit in Prod. I connected our 10g and our 1g networks with a virtual switch in a Proxmox server. I undid it shortly after that, but it caused a network storm that impacted customers in 2 datacenters.

      Fiber is unidirectional. The long run shit has two cables, for up and down. The graphic was supposed to show one of those two cables being cut. (I don’t think it shows that very well.)
