Standard and Enhanced Policy Considerations

This section itemizes additional policy considerations for the stackable and standalone platforms, and provides a table cross-referencing standard and enhanced policy capability and policy capability to traffic classification rules.

Not all stackable fixed switch platforms support policy. On some stackable and standalone fixed switch platforms policy support requires a purchased license. See the software release notes that come with your device for policy support.

Standard and Enhanced Policy Capability Cross-Reference provides a listing of policy capabilities by standard and enhanced support level. Standard policy capabilities are further granulated based upon traffic classification support. See Policy Capability to Traffic Classification Rule Cross-Reference for a cross-reference of traffic classification to policy capability support.
