[SOLVED] Setup Management port at high speed

[Lucas Rey]

Hello community, I moved the Proxmox management port to a 10Gb card. Proxmox/Debian detects the supported speed at 10000baseT/Full, but Speed is setup as 1000Mb/s. How can I change such speed and take advantage of the full 10Gb speed?

# ethtool mgmt0
Settings for mgmt0:
        Supported ports: [ TP ]
        Supported link modes:   100baseT/Full
                                1000baseT/Full
                                10000baseT/Full
        Supported pause frame use: Symmetric Receive-only
        Supports auto-negotiation: Yes
        Supported FEC modes: Not reported
        Advertised link modes:  100baseT/Full
                                1000baseT/Full
                                10000baseT/Full
        Advertised pause frame use: No
        Advertised auto-negotiation: Yes
        Advertised FEC modes: Not reported
        Speed: 1000Mb/s
        Duplex: Full
        Auto-negotiation: on
        Port: Twisted Pair
        PHYAD: 0
        Transceiver: internal
        MDI-X: Unknown
        Supports Wake-on: d
        Wake-on: d
        Current message level: 0x00000007 (7)
                               drv probe link
        Link detected: yes

I tried this, but it fails:

# ethtool -s mgmt0 speed 10000 duplex full
netlink error: link settings update failed
netlink error: Operation not supported

Thank you
Lucas

EDIT: Damn! Find it. The Management port is connected to a 2,5Gb switch, but such speed is not supported by network card, so that's why I got 1000MB/s.
Sorry to waste forum space! ^_^
