Data center bridging eXchange

Data center bridging eXchange (DCBX) allows a switch to:
  • Discover DCBX- enabled peers automatically.
  • Detects misconfiguration in the DCBX-enabled peers.

In a converged data center network, DCBX provides plug-and-play capability for server, storage, and networking devices in an end-to-end solution. DCBX also ensures the consistent and efficient operation.

DCBX uses link layer discovery protocol (LLDP) to mediate automatic negotiation and device settings exchange, such as PFC and ETS. DCBX uses LLDP TLVs to perform DCB parameter exchange:
  • PFC configuration and application-priority configuration
  • ETS configuration and ETS recommendation

This sample DCBX topology shows two 40GbE ports on a switch that are used as uplinks to top-of-rack (ToR) switches. The ToR switches are part of a fiber channel storage network.
