    Hello,

    I found something in another post and have not been able to locate it again, but recently I have a switch that started to give me the following errors in the log:

    I 09/04/22 03:31:07 00077 ports: port 15 in Trk1 is now off-line

    At first I thought it was something with the patch cables or transceivers, but I did replace them both on both sides of the connection and I still see the log messages. IT isn't stopping anything and I don't think anyone has noticed it yet, but I am having some trouble narrowing it down. It just started and we have not had any issues for the last 2 years with this connection. There have not been any changes made either.

    Port 15 is setup as an LACP trunk (trunk 15 trk1 lacp). I do see at the end of sho run this: spanning-tree Trk1 priority 4. I was thinking that might be what is causing my problem, but I am not sure and like I said, there have been no modifications to this connection or the switch...

    Blocked by LACP suggests to me that the other side is not sending LACP packets.

    Do you have more ports than port 15 on your Trk1?

    For completeness, a Trunk in ArubaOS Switch is what in some other switches is called a portchannel or etherchannel, it's bundling multiple physical links to a single logical link for increased capacity or link redundancy. Having a trunk with a single interface doesn't make sense in most cases.
