For any IPMI enabled servers also needing a private VLAN set up, Dual Mode VLAN port support for both the IPMI switch port (having IPMI VLAN as tagged and private VLAN as untagged) and IPMI BIOS (using failover option) needs to be updated for things to work correctly. In addition, the VLAN ID on the IPMI Console page also needs to be enabled to use the IPMI VLAN #.
