Severity: 3-Major


The vCMP guests running on blades in a single chassis report different MAC addresses on a single VLAN upon host reboot for the vCMP guest.


Incorrect MAC addresses are reported by some blades.


This issue may be seen when all of the following conditions are met: -- One or more blades are turned off completely via AOM. -- There are two VLANs. -- You deploy a multi-slot guest with the higher lexicographic VLAN, and assign the lower VLAN to the guest. -- Reboot the host.



Fix Information

There is no longer a vCMP guest VLAN MAC mismatch across blades under these conditions.
