Version Incompatibilities for Path Selection
SCC 9.0 and later don’t support path selection-policy pushes for SteelHead 8.0, 9.0.x or later or SteelHead EX 2.0 and 3.6.x or later.
If you’re running this version of the software on your remote appliance, you must create a new set of path selection rules based on sites, networks, and uplinks to apply to simplified QoS or secure transport. For details about creating sites, networks, and uplinks, see Managing Interceptor clusters. For details about configuration path selection in the SCC, see Managing path selection.
