Hi all,
Is there something new regarding this issue?
We have the same problem in our network.
Our server is currently connected to the backside 10gb Ports of a 2920 stack using 3m dac cable.
Now we tried to move them to two 2930f vsf switches with the same issue.
The switch recognizes the dac cable and the link is shown as up but there is no communication possible.
The 2920 and the 2930f are running firmware 16.5.7
Also there is no special I formation in the log file available.
Just insertion of the transceiver and then status up from the port.
Regards
