HP Network Optimizer SDN Application - Microsoft Lync 1.0 Administrator Guide

Best Effort Reasons—Out of Resources
Possible causes include:
• There is a FlowMod error.
A FlowMod error is a configuration error on the switch that prevents flows from receiving
DSCP values.
• The flow table is full.
A flow table records network activities on the switches, including but not limited to Net
Optimizer - Lync activities. When a flow starts, it appears as an entry in the flow table until it
ends.
If the flow table is full, new flows cannot be marked with DSCP values. After a flow ends, the
corresponding entry in the flow table is cleared, thus making it possible for a new flow to get
in and be marked with DSCP value.
License statuses in the Lync session table

as shown in Figure 17, it means the switch with such Source DPID/Port or Dest DPID/Port is a
non-OpenFlow switch and thus cannot be recognized.
