Configuring DCBX

Data Center Ethernet (DCE), also known as Converged Enhanced Ethernet (CEE), is enhancement and expansion of traditional Ethernet local area networks for use in data centers. DCE uses the Data Center Bridging Exchange Protocol (DCBX) to negotiate and remotely configure the bridge capability of network elements.

DCBX has the following self-adaptable versions:

DCBX offers the following functions:


[NOTE: ]

NOTE:

HPE devices support only the remote configuration function.


Figure 80: DCBX application scenario

DCBX enables lossless packet transmission on DCE networks.

As shown in Figure 80, DCBX applies to an FCoE-based data center network, and operates on an access switch. DCBX enables the switch to control the server's or disk device's adapter, and simplifies the configuration and guarantees configuration consistency. DCBX extends LLDP by using the IEEE 802.1 organizationally specific TLVs (DCBX TLVs) to transmit DCBX data, including:

HPE devices can send these types of DCBX information to a server's or disk device's adapter supporting FCoE, but they cannot accept them.
