Cause:

Cisco's Nexus 1000v is trying to reserve the multicast MAC address on NetQueue enabled NICs, however bnx2x driver doesn't support this feature therefore it fails the "applyRxFilter" call.

 

 

 

 

 

Environment

VMware Update Manager 6.0
VMware vCenter Server 6.0.x
VMware vCenter Server Appliance 6.0.x
VMware vSphere ESXi 6.0
VMware vCenter Converter Standalone 6.x

Resolution

To resolve this Issue, perform below steps.

 

1. Disable NetQueue, however NetQueue might be necessary in some network implementations and disabling it might result in connectivity issues.
    
2. Migrate to a VMware dvSwitch instead of a Nexus 1000v
