Rokabear offers redundant network connections to dual switches, in the event of a switch failure.

As such the Network Interface cards need to be configured to take advantage of this feature.

Note: Rokabear VPS products do not need to perform this configuration as the host servers are already configured for failover.

 

Rokabear strongly urges anyone who does not have remote console, remote KVM, or other similar device on their machine to notify and schedule this change with Rokabear technical staff.

Rokabear wants to ensure that staff is available and on hand in case of a configuration error so that we can minimize your downtime.  That being said, we have performed this setup many times and it works well.
