The ExtremeWare Enterprise Manager Policy System lets you work with high-level
components, or policy objects, when defining a QoS policy. The components used
within the Enterprise Manager Policy System are the following:
• Devices (by name) and Device Groups: These are entered into the Enterprise
Manager database via the Inventory Manager (Discovery or Add Devices), and are
mapped to IP addresses in the Enterprise Manager database.
• End Stations (by name) and End Station Groups: These are entered into the Policy
System, through the Import capability or individually using the GUI. End Station
Groups are sets of individual End Stations that are grouped to allow them to be
acted upon as a unit. The individual End Stations are mapped to IP addresses
through Network Name Lookup Services, or can be mapped manually using the
GUI. Within the Policy System the IP addresses are mapped to physical ports on an
Extreme switch using DLCS, or the mapping can be specified manually.
• Users (by name) and User Groups: These are also entered into the Policy System,
through the Import capability or individually using the GUI. User Groups are sets of
individual Users that are grouped to allow them to be acted upon as a unit. The
individual Users are mapped to End Stations, either via DLCS or manually using the
GUI. The End Stations are then mapped to IP addresses and physical ports as
described above.
• Port Groups: These are defined in the Inventory Manager, and enable a set of ports
(from different devices, if appropriate) to be acted upon as a group.
• VLANs: These are detected by the Enterprise Manager, and can also be created and
modified using the VLAN Manager applet. They cannot be modified within the
Policy System.
• Subnets: Subnet specifications can be used within a Custom Policy definition. They
must be entered manually using the dotted quad notation.
• Applications: These are named entities (such as Baan, FTP, HTTP) that map to Layer
4 well-known ports. They cannot be modified within Enterprise Manager.
• Treatments: These are definitions of priority, minimum and maximum bandwidth
that are combined with an application or a set of end point components to define a
policy. Treatments are predefined, but they can be modified within the Policy System
GUI.
These policy objects must defined before they can be used in a policy. IP addresses,
Layer 4 ports, and subnets can be typed directly into a policy without any
pre-definition.
