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.

Table 1. Standard and Enhanced Policy Capability Cross-Reference

Policy Support Level	Policy Capability
Standard	Dynamic PID Assign Rule – The ability to dynamically assign a policy based upon a traffic classification (macsource and port-string). See Dynamic in Policy Capability to Traffic Classification Rule Cross-Reference. Admin PID Assign Rule – The ability to administratively assign a policy based upon a traffic classification (macsource and port-string). See Admin in Policy Capability to Traffic Classification Rule Cross-Reference. VLAN Forwarding – The ability to assign a forwarding VLAN rule through the default profile/role PVID only. Deny – The ability to assign a drop traffic rule. See Drop in Policy Capability to Traffic Classification Rule Cross-Reference. Permit – The ability to assign a forward traffic rule. See Forward in Policy Capability to Traffic Classification Rule Cross-Reference. CoS Assign Rule – The ability to assign a CoS rule. See CoS in Policy Capability to Traffic Classification Rule Cross-Reference. Priority – The ability to assign traffic priority using a CoS assignment. See CoS in Policy Capability to Traffic Classification Rule Cross-Reference. Longest Prefix Rules – The ability to always look at the highest bit mask for an exact traffic classification match.
Enhanced	TCI Overwrite – The ability to overwrite user priority and other VLAN tag TCI field classification information. Invalid Policy Action – The ability to set a drop, forward, or default-policy behavior based upon an invalid action.

Policy Capability to Traffic Classification Rule Cross-Reference provides a cross-reference of standard ( ) and enhanced (X) policy capability to traffic classification rule.
