Bugs Affecting the Oracle VM Server for SPARC 3.3.0.1 Maintenance Update Release

Language:

The bugs described in this section might also affect the Oracle VM Server for SPARC 3.3 software.

Virtual Functions Might Experience Malicious Behavior When Using Some Intel Network Adapters

When using some Intel network adapters that support SR-IOV, a virtual function might be the target of malicious behavior. Unexpected software-generated frames can throttle traffic between the host and the virtual switch, which might negatively affect performance.

Workaround: Configure all SR-IOV-enabled ports to use VLAN tagging to drop unexpected and potentially malicious frames.

To configure VLAN tagging on a physical function and its associated virtual functions, use the following command:
```
ldm create-vf [pvid=pvid] [vid=vid1,vid2,...>] net-pf-name
```
To configure VLAN tagging on an existing virtual function, use the following command:
```
ldm set-io [pvid=[pvid]] [vid=[vid1,vid2,...]] net-vf-name
```
