hi Andre,
i am using hp procurve 2610
FYI, i am using port 17 for the first esxi (which is working) and port 13 for second esxi (which is not working).
i have already physically swapped the cable for the two esxi.
port 13 (the first esxi) - working
port 17 (the second esxi) - still not working.
does this still show that it is a switch port issue?
