DCBx Example
The following gure shows how DCBX is used on an MXL Switch installed in a PowerEdge M1000e chassis in which servers are also
installed.
The external 40GbE ports on the base module (ports 33 and 37) of two switches are used for uplinks congured as DCBx auto-upstream
ports. The MXL switch is connected to third-party, top-of-rack (ToR) switches through 40GbE uplinks. The ToR switches are part of a
Fibre Channel storage network.
The internal ports (ports 1-32) connected to the 10GbE backplane are congured as auto-downstream ports.
On the MXL switch, PFC and ETS use DCBx to exchange link-level conguration with DCBx peer devices.
