802.1Qcd – Application VLAN TLV

The full title of this PAR is “Standard for Local and metropolitan area networks–Media Access Control (MAC) Bridges and Virtual Bridged Local Area Networks Amendment: Application Virtual Local Area Network (VLAN) Type, Length, Value (TLV)”.

This standard specifies the protocols, procedures, and management objects for an Application Virtual Local Area Network (VLAN) identifier (ID) Type, Length, Value (TLV) within the Data Center Bridging eXchange (DCBX) protocol defined in IEEE Std 802.1Qaz.

MAC Bridges, as specified by this standard, allow the compatible interconnection of information technology equipment attached to separate individual LANs.

For networks that already make use of DCBX, an Application VLAN ID TLV will simplify the management of the end station by allowing the VLAN ID for the application to be communicated via DCBX rather than requiring manual configuration. Converged network deployments where multiple networks such as LAN/Storage/High Performance Computing (HPC) are operated over the same physical infrastructure make use of the DCBX protocol to provision services such as Priority-based Flow Control (PFC), Enhanced Transmission Selection (ETS), and Application Priority. In these deployments, it is highly desirable to be able to provision the VLAN ID for an application via DCBX, instead of requiring manual provisioning.
