Usage guidelines
For DCBX to work correctly, set the same DCBX version on the local port and peer port. As a best practice, set the highest version supported on both ends. IEEE Std 802.1Qaz-2011, DCBX Rev 1.01, and DCBX Rev 1.00 are in descending order.
After the configuration, LLDP frames sent by the local port carry information about the configured DCBX version. The local port and peer port do not negotiate the DCBX version.
When the DCBX version is autonegotiated, the version IEEE Std 802.1Qaz-2011 is preferentially negotiated.
Examples
# Set the DCBX version to Rev. 1.01 on interface .
<Sysname> system-view [Sysname] interface [Sysname-] dcbx version rev101
