Please note: The problem described in this software defect is about that we dont correctly create a piece of the binary configuration in the Nexus switch when we turn the dcbx off on the switch and save the configuration. The fix in this software defect is to create this part of the binary confiuration correct. However when you upgrade from a impacted version to a fixed version, i.e. 7.0(3)N1(1) has the fix, we do NOT automatically create the correct binary key. The user needs to do the following after the upgrade, and it does not matter if that upgrade is done disruptive or non disruptive. lldp tlv-select dcbxp no lldp tlv-select dcbxp copy running-config startup-config With the first command you turn dcbx back on, then we turn it back off to make sure that the runtime status is turned off, and then with the saving of the configuration we generate the correct binary configuration. From then on going forward you can reload the switch or upgrade in the future to a higher version without impacting the configuration of dcbx.
