How to enable auto-negotiation on your Self-Managed Server

The uplink speed of our Self-Managed Servers will be increasing from 100Mbps to 1Gbps at our Cape Town Data Centre. For hosts to achieve full-duplex operation following the upgrade maintenance, speed and duplex configuration settings will need to be removed and your Self-Managed Server will need to be rebooted.

If you do not wish to reboot your server, the below step will be needed to enable auto-negotiation.

Linux Server

Auto-negotiation can be enabled from the shell command prompt with the following command:

ethtool -s <network_interface> autoneg on

Windows Server

Set the “Speed & Duplex” setting to Auto.
