Two trunks on the same port group

  • 1.  Two trunks on the same port group

    Posted 28 days ago

    This is crazy, I have two ISLs on the same port group, but they are forming two trunks with two masters, instead of a single trunk. First, ports 19 on both switches was configured with L0 distance config, I've set it to LE as configured with the other port pair 23 (trunk between two sites), I've set the correct long-distance mode, I've even made sure taht the speed is set to auto, no QoS is cofigured, but they refuse to merge. By the way, I have another favric, same config, and the trunk works their fine.

    Interesting. I've not seen this one.

     

    What I would do after reviewing all the ports in the trunk to ensure there arent any other errors:

     

    portdisable 23

    portcfgdefault 23

    portenable 23

    Hello again, your tip did the trick for me. but I had to reset all four ports to factory defaults, reconfigured trunking and LE, and it worked fine, a single trunk.

    Thanks again,
