To configure an ISA-AA group and ISA-AA partitions

Purpose

Perform this procedure to create an ISA-AA group that contains one or more partitions. ISA-AA partitions provide ISA-AA group functions that are limited to the partition scope.

Note: When you create an ISA-AA group or partition, a default AA policy is automatically created for the group or partition. When you delete a group or partition, the default policy is also deleted.

Steps


1	On the Equipment tree, expand [NE]→Logical Groups→ISA-AA Groups.
2	Right-click on the ISA-AA Groups icon and choose Create ISA-AA Group, or right-click an existing ISA-AA group object and choose Properties. The ISA-AA Group (Create\|Edit) form opens.
3	Configure the required parameters. If the ISA-AA group is to be added to an ISA-WLAN GW, you must set the Subscriber Scale parameter to Lightweight Internet. If you are configuring an existing AA group and the associated AA group policy has SAP dependencies, you cannot modify the Partitions parameter until you remove the SAP dependencies on the group policy. The following parameters are configurable when the Subscriber Scale parameter is set to something other than Lightweight Internet: Number of IPv4 Transit Prefix Entries Number of Remote IPv4 Transit Prefix Entries Number of IPv6 Transit Prefix Entries Number of Remote IPv6 Transit Prefix Entries
4	Click Apply.
5	Click on the AA Group Members tab to specify one or more AA group members for the ISA-AA group. Note: The available group member type depends on the Subscriber Scale parameter: each subscriber scale model is applicable to either ISA or ESA only. To add an ISA-AA MDA as an AA group member, see Step 6. To add an ESA VM as an AA group member, see Step 7.
6	Click on the AA Group Members tab to specify one or more ISA-AA MDAs for the ISA-AA group. Click Create or select an existing AA group member entry and click Properties. The AA Group Member (Create\|Edit) form opens. Configure the Role parameter. If the ISA-AA group is to be included for Distributed Subscriber Management in an ISA-WLAN GW group, you must set the Role parameter to Primary for each group member. Select a member MDA. After a reboot, an NE rebalances the AA processing load. Because of this, the MDA slot number assigned to an AA subscriber or AA SAP on the AA Subscriber or AA SAP Summary form is displayed as Unassigned if the AA subscribers in the configuration file cannot be accommodated. Save your changes and close the form. Proceed to Step 8.
7	Click on the AA Group Members tab to specify one or more ESA VMs for the ISA-AA group. Click Create or select an existing AA group member entry and click Properties. The AA Group Member (Create\|Edit) form opens. Select a member VM. The VM type of the selected member VM must be Application Assurance. Save your changes and close the form. Proceed to Step 8.
8	Click on the ISA-AA Group Diverted FCs tab to specify one or more traffic forwarding classes to divert to the ISA-AA group. Click Create or select an existing ISA-AA group diverted forwarding class entry and click Properties.The ISA-AA Group Diverted FC (Create\|Edit) form opens. Configure the Forwarding Class Name parameter. Save your changes and close the form.
9	Click on the QoS tab to configure QoS policy parameters for the ISA-AA group. Configure the required parameters on the Egress From-Subscriber tab. You must deselect the Default check box before you can use a slider to specify a Reserved CBS or Buffer Utilization High Water Mark value. The value of the Buffer Utilization High Water Mark parameter must be higher than the value of the Buffer Utilization Low Water Mark parameter. Select a slope policy in the Slope Policy panel. Select a network queue policy in the Network Queue Policy panel. Select a port scheduler policy in the Port Scheduler Policy panel. Click on the Egress To-Subscriber tab and repeat Step 9 1 to 4 .
10	You can configure the following objects on the ISA-AA group if the Partitions parameter was disabled in Step 3 . AA subscriber statistics ( To configure AA subscriber statistics collection on an ISA-AA group or partition ) AA special study objects ( To configure special study objects on an ISA-AA group or partition ) AA subscriber policy override ( To configure an AA subscriber policy override on an ISA-AA group or partition )
11	To configure Cflowd on the ISA-AA group, click on the CFLOWD tab and perform To configure Cflowd collectors on an ISA-AA group or partition.
12	If the Partitions parameter on the General tab is enabled in Step 3 , click on the ISA-AA Partitions tab to configure AA partitions for the group. Click Create or select an existing partition entry and click Properties. The ISA-AA Group Partition (Create\|Edit) form opens. Configure the required parameters. Click on the CFLOWD tab to configure Cflowd on the partition (See To configure Cflowd collectors on an ISA-AA group or partition . The following objects are configurable on ISA-AA group partitions: AA subscriber statistics ( To configure AA subscriber statistics collection on an ISA-AA group or partition ) AA special study objects ( To configure special study objects on an ISA-AA group or partition ) AA subscriber policy override ( To configure an AA subscriber policy override on an ISA-AA group or partition )
13	Save your changes and close the forms. End of steps
