Fixed In:

Opened: Jul 12, 2016
Severity: 3-Major

Symptoms

Your vCMP guests are unable to reach the network. You see in /var/log/ltm "mcpd[5503]: 01071322:4: Vlan allowed mismatch found: hypervisor "

Impact

Unable to use VLAN.

Conditions

When a VLAN exists in the vlan-allowed list contains a VLAN which matches the suffix of another VLAN in the list and both VLANs are configured on the VCMP guest. For example, xyz and abc_xyz will produce the error "warning mcpd[6374]: 01071322:4: Vlan allowed mismatch found: hypervisor (abc_xyz:1860), guest (/Common/xyz:1850)."

Workaround

Rename the VLANs such that no VLAN matches suffix of any other VLAN.

Fix Information

None

Behavior Change
