It provides fallback for IE8.

How does HP Network Optimizer SDN Application improve quality forMicrosoft Lync traffic?

It dynamically configures controlled switches to prioritize the voice and video traffic flows based on session information from the controller. ✘ It is pre-programmed with the correct sets of TCP and UDP ports for Lync traffic; it automatically deploys the correct QoS maps to controlled switches. ✘ It configures Lync clients to automatically prioritize their traffic correctly, and it configures switches to trust this prioritization. ✘ It uses deep packet inspection (DPI) analysis to identify voice and video traffic; it then dynamically configures switches to prioritize this traffic. ✔

An HP ProVision switch loses its OpenFlow connection to the HP VANSDN Controller. How is traffic processed by default if no controller teaming is configured?

Packets and messages destined to the controller are dropped. Flows continue to expire according to their time-outs. This is because the default setting on HP ProVision switches is fail-secure. ✘ Packets and messages of new flows behave as a legacy switch or router would. Existing flows of this OpenFlow instance are removed. This is because the default setting on HP ProVision switches is fail-secure. ✘ Packets and messages destined to the controller are dropped. Flows continue to expire according to their time-outs.
