Severity: 3-Major


On iSeries platforms, when a VLAN is attached to a vCMP guest, the management MAC address and the host VLAN MAC address will be the same.


The management MAC address is the same as the Host VLAN MAC address, resulting in the same MAC being used for the VLAN traffic originating from the vCMP Host along with the Host's mgmt Interface traffic, potentially resulting in issues relating to the inability to differentiate traffic to mgmt port or traffic ports.


-- Creating a VLAN on the host and attaching it to a vCMP guest. -- iSeries platforms.


There is no workaround at this time.

Fix Information

The management MAC address and Host VLAN MAC address are now different on iSeries platforms, so the system can differentiate traffic as expected.
