OLICY BASED UALITY OF
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. Leveraging
ExtremeWare 5.0's Policy-Based Quality of Service (QoS) capabilities, the ExtremeWare
Enterprise Manager Policy System offers a powerful set of easy-to-use policy
management tools that meet the application-specific needs of today's networks.
Through ExtremeWare Enterprise Manager's Policy System Client, policies can be
defined in terms of individual applications, users and desktop systems, not just by IP or
MAC addresses.
The ExtremeWare Enterprise Manager Policy System lets you work with high-level
policy objects (users, desktop systems, groups of users or systems, applications, and
groups of devices and ports) in defining policies. The policy system translates those
policy objects 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.
To facilitate policy-setting based on user names or individual desktop systems, the
Policy System takes advantage of the Dynamic Link Context System (DLCS) to map a
user's name or system to the associated IP and MAC addresses.
The policy system also supports limited policy configuration for third-party
devices—specifically selected Cisco devices and Xedia switches as of ExtremeWare
Enterprise Manager release 2.0.

IMPLE NVENTORY
The ExtremeWare Enterprise Manager's Inventory Manager applet keeps a database of
all the devices managed by the Enterprise Manager. Any Enterprise Manager user can
view status information about the switches currently known to Enterprise Manager.
The ExtremeWare Enterprise Manager 2.0 software provides an automatic discovery
function. Users with the appropriate access can use this feature to discover Extreme,
Cisco, and Xedia devices by specific IP address or within a range of IP addresses.
Network devices can also be added to the Enterprise Manager database manually, using
the Inventory Manager Add function. Once a network device is known to the Enterprise
Manager database, you can assign it to a specific device group, and configure it using
the VLAN Manager, Virtual Chassis Stack Manager, ExtremeView, or the Policy System.
