Policy Manager Overview
This chapter describes:
• An overview of the Policy Manager features
• An introduction to the concepts that are fundamental to creating policies using the EPICenter Policy
Manager
Overview of the Policy Manager
Policy-based management is used to protect and guarantee delivery of mission-critical traffic. A
network policy is a set of high-level rules for controlling the priority of, and amount of bandwidth
available to, various types of network traffic. Using EPICenter, policies can be defined in terms of
individual users and desktop systems, not just by IP or MAC addresses, ports, or VLANs.
The EPICenter Policy Manager lets you work with high-level policy components (users, desktop
systems, groups of users or systems, applications, and groups of devices and ports) in defining policies.
The policy system translates those policy components into the specific information needed for QoS
configuration of network devices. It also detects overlaps and conflicts in policies, with precedence rules
for resolving conflicting QoS rules.
NOTE
The EPICenter policy system is based on the policy-based QoS capabilities in the ExtremeWare
software. For details on the capabilities and implementation of QoS in Extreme Networks switches, see
the ExtremeWare Software User Guide or the ExtremeWare Release Note for the version(s) of the
software running on your switches.
The EPICenter Policy Manager is a separately-licensed component of the EPICenter product family.
When a Policy Manager license is installed on the EPICenter server, the Policy icon appears in the
Navigation Toolbar at the left of your browser window.
If no icon is present, it indicates that no current license can be found for the Policy Manager module.
See the
EPICenter Installation and Upgrade Note or the EPICenter Release Note for information on obtaining
and installing a license.
