Hi,
I have a server with two Intel x552 SFP+ interfaces. These contain 2 Intel 1Gb/10Gb dual speed SFPs (Intel official). The server is running ESX and it states that the interfaces are connected, running 1Gb.

The other side is connected is connected to a 2960x SFP port, containing a GLC-SX-MMD. But I also tried a 2960S. Both switch run the latest IOS. Cables used are OM3 MM (2m)
On the Cisco side, is shows 'notconnect':

However, running diagnostics, it shows a connection:

If I switch cable end, I get a -40 value for the diagnostics (no connection) so I think I can assume cabling is okay.
The port config is:
interface GigabitEthernet1/0/28
switchport trunk allowed vlan 98,99,101,102
switchport mode trunk
switchport nonegotiate
spanning-tree portfast edge trunk
end
Also tried with switchport nonegotiate.
What could be the issue?
