Use this window to define the Class of Service (CoS) configuration you want to use in the current domain. To access this window, select Class of Service Configuration from the Policy Manager Edit menu.
When you first install Policy Manager, this window is pre-populated with eight static classes of service, each associated with one of the 802.1p priorities (0-7). You can use these predefined classes of service or create your own classes of service.
You can also use this window to define inbound and outbound rate limits and outbound transmit queue rate shapers for your classes of service.
After you have created and defined your classes of service, you can assign them as a classification rule action, a role default, or as part of the definition of an automated service. See Getting Started with Class of Service and How to Create a Class of Service for more information.
Click the graphic for more information.
Use the Create menu to create a new class of service, or a new rate limit or transmit queue rate shaper port group. For more information on port groups, see Creating Class of Service Port Groups.
Use this menu to specify which CoS component columns you would like displayed in the table. For example, if you want to view the inbound rate limits that are configured, you can select to display only Inbound RL, making it easier for you to focus in on the desired information. You can also filter by port group name. For example, if you have created two port groups named Edge and Core for your Inbound RL, Outbound RL, and TxQ Shapers, selecting Core from the menu will display only the IRL/ORL/TxQ settings for the Core group in the table.
Use this menu to specify the CoS components you will be configuring for this domain. This will determine what CoS settings will be written to your network switches on Enforce. For example, if you select only Inbound RL and Outbound RL, then Policy Manager will enforce the rate limits you configure, but will not overwrite any transmit queue settings configured on the device via the Command Line Interface (CLI).
Use the Show all CoS components in tree (Advanced Mode) option to display the individual CoS components in a left-panel tree. The Advanced Mode allows you to change the rate limit and transmit queue index numbers associated with the class of service, as well as map different rates to different port types in your rate limit port groups.
| TIP: | For many of the values below, hovering over the value in the table will show a tooltip with more information about the current settings. |
The name of the class of service.
The index number automatically assigned to the class of service.
The 802.1p priority associated with the class of service. Double-click a priority to select a new priority, if desired. The priority for the eight static classes of service provided by Policy Manager (Priority 0-7), cannot be disabled or changed.
The IP type of service value associated with this class of service, if any. See IP Type of Service for more information. Double-click in the ToS column to enter a ToS value or open the ToS/DSCP Configuration window.
The drop precedence associated with this class of service. Double-click in the column to select a Drop Precedence value: Low, Medium, or High.
The port inbound rate limit (IRL) that is configured for the Default port group, if any. If you have created additional port groups, the rate limits will be displayed for those groups as well. Double-click in the column to set or change a rate for each class of service. Right-click on the Inbound RL column heading to create a new Inbound RL port group. Then, right-click on the port group name to open the Add/Remove Ports window to assign which port will be in each group.
The port outbound rate limit (ORL) that is configured for the Default port group, if any. If you have created additional port groups, the rate limits will be displayed for those groups as well. Double-click in the column to set or change a rate for each class of service. Right-click on the Outbound RL column heading to create a new Outbound RL port group. Then, right-click on the port group name to open the Add/Remove Ports window to assign which port will be in each group.
The rate shaper that is configured for the Default port group, if any. If you have created additional port groups, the rate shaper will be displayed for those groups as well. Double-click in the column to set or change a rate for each class of service. Right-click on the TxQ Shaper column heading to create a new TxQ Shaper port group. Then, right-click on the port group name to open the Add/Remove Ports window to assign which port will be in each group.
The Queue column displays the transmit queue associated with the class of service for each port type. Double-click the queue to see a drop-down menu where you can select a new transmit queue, if desired. The Bandwidth column displays the arbiter mode configuration for all queues. Double-click the Bandwidth column to open the Edit Bandwidth Configuration Window where you can configure the arbiter mode for all queues. If you have used advanced mode to configure different arbiter modes for multiple transmit queue port groups, the Bandwidth column will display "Advanced".
The Flood Control column displays the rate limit for incoming traffic configured for each of the following traffic types (unknown-unicast, broadcast, or multicast). While Flood Control rates can be changed by editing a cell for a class of service, these rates are shared globally by all CoS in the domain. All Flood Control enabled CoS will share these rates. When Flood Control configuration is edited, all affected CoS will have their cells highlighted. Double-click in the column to set or change the rate for each type. To leave the Flood Control rates and just enable or disable Flood Control for a CoS, select Enable or Disable Flood Control from the drop-down menu.
| NOTE: |
By default, Flood Control is not managed by Policy Manager. To manage flood control configuration on devices in a domain, it can be enabled via the Domain Managed CoS Components drop-down menu by selecting All CoS Components or by selecting Flood Control. |

If you have ExtremeWireless Wireless Controllers on your network, this column displays the inbound rate limit that is configured for the Default port group, if any. Double-click in the column to set or change a rate for each class of service. Currently, user-based rate limits are only available for wireless controllers.
If you have ExtremeWireless Wireless Controllers on your network, this column displays the outbound rate limit that is configured for the Default port group, if any. Double-click in the column to set or change a rate for each class of service. Currently, user-based rate limits are only available for wireless controllers.
