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.
