  • Traffic Shaping

  • NIC teaming

Policies can be defined either at the standard virtual switch level, or at the port or port group level. The policies applied at the port group level over ride the policies (or take precedence over the policies) applied at the virtual switch level. Hence, it is advisable to implement all major and critical policies at the port group level.
