    Weird issue

    Update... i replaced the Netgear switch with an Arista DCS-7050T-64 and have the same issue. Is there software that can monitor all ports and log issues? or will i literally have to connect 1 port at a time and wait to find the line that's the culprit? (will take a long time with 40+ ports :( )
