ONEPolicy Overview

The three primary benefits of using policy in your network are provisioning and control of network resources, security, and centralized operational efficiency. Policy provides for the provisioning and control of network resources by creating policy roles that allow you to determine network provisioning and control at the appropriate network layer, for a given user or device. With a role defined, rules can be created based upon up to 15 traffic classification types for traffic drop or forwarding. A CoS (Class of Service) can be associated with each role for purposes of setting priority, forwarding queue, rate limiting, and rate shaping.

Security can be enhanced by allowing only intended users and devices access to network protocols and capabilities. Some examples are:

Ensuring that only approved stations can use SNMP, preventing unauthorized stations from viewing, reading, and writing network management information
Preventing edge clients from attaching network services that are appropriately restricted to data centers and managed by the enterprise IT organization such as DHCP (Dynamic Host Configuration Protocol) and DNS services
Identifying and restricting routing to legitimate routing IP addresses to prevent DoS, spoofing, data integrity and other routing related security issues
Ensuring that FTP/TFTP file transfers and firmware upgrades only originate from authorized file and configuration management servers
Preventing clients from using legacy protocols

Extreme Management Center Policy Manager provides a centralized point and click configuration, and one click pushing of defined policy out to all network elements. Use Extreme Management Center Policy Manager for ease of initial configuration and response to security and provisioning issues that may come up during real-time network operation.

Note

When OnePolicy is enabled certain MPLS (Multiprotocol Label Switching), PSTag, VXLAN, and OpenFlow configurations may not operate.

Note

Configuration changes on existing policy mux entries (changing the policy profile for a convergence endpoint to 0 or a different value, disabling Link Layer Discovery Protocol or CDP, etc.) do not take effect until re-authorization. As a result, existing CEP connections remain active and FDB (forwarding database) is still learned on policy profile even though CDP/LLDP neighbor times out and show cdp neighbor {detail} and show lldp neighbors is empty. You can force re-authorization by clearing a CEP connection: configure policy convergence-endpoint clear ports [port_list | all].

Note

If you configure multiple authentication types, failure of a higher priority authentication results in the lower priority authentication being used.
