Managing Your Network : Managing Interceptor Clusters : Adding a Cluster Using the Wizard
  
Adding a Cluster Using the Wizard
You define a cluster in the Clusters page. A configuration wizard guides you through the initial configuration of a cluster. After you run the wizard, you can customize additional appliance cluster settings, such as modifying the topology or adding Interceptors or SteelHeads. You can add up to four-path clusters using the configuration wizard.
After the cluster is named, that name cannot be changed in the wizard. To change the cluster name, click Run cluster wizard to make any changes to the settings. For details about editing a cluster, see Configuring Path Selection on Interceptor Clusters.
Before configuring the system topology, read the deployment information available in the SteelHead Interceptor Deployment Guide.
Note: The cluster configuration can automatically generate certain policy pages for appliances in the cluster.
To add a cluster using the wizard
1. Choose Manage > Topology: Clusters to display the Clusters page.
2. Click + Add a New Cluster to expand the page.
3. Click Launch Cluster Configuration Wizard to launch the wizard and display the Welcome page.
4. Click Next to display the Basic Cluster Settings page and complete the configuration as described in this table.
Setting
Description
Cluster Name
Specify the name of the cluster.
Comments
Optionally, include a description to help you administer the cluster. Descriptions must not use any character other than letters, numbers, underscore, space, or backslash (directory separator).
5. Click Apply & Continue to display the Topology Settings page and complete the configuration as described in this table.
Setting
Description
Select Topology
Select the topology you want to deploy:
•  1 path (maximum 2)
•  2 paths (maximum 4)
•  3 paths (maximum 6)
•  4 paths (maximum 8)
If you are using multiple Interceptors, configure them as part of the cluster.
For detailed information about topology settings, see the SteelHead Interceptor Deployment Guide.
Add Interceptors
Specify your Interceptors.
•  Primary Interceptor - Select the primary Interceptor from the drop-down list.
•  Failover Interceptor - Optionally, select a failover Interceptor when there are pairs of serially connected Interceptors.
For failover you deploy two Interceptors physically in-path on all of the same physical links, and each appliance is configured to act as a backup for the other appliance for the same network links. If one appliance goes down or needs maintenance, the failover appliance redirects the connections over those links. For details about configuring failover, see the SteelHead Interceptor User’s Guide.
6. Click Next to display Other Topology Settings page, and complete the configuration as described in this table.
Setting
Description
Connection Forwarding Settings
Select Optimize Connections When Connection Forwarding Interceptor Not Connected to configure an optimization cluster with other Interceptors in the network.
To enable your neighbor, SteelHeads must have the in-path neighbor failure feature enabled.
Connection forwarding defines how the appliance communicates with the other Interceptors or appliances in the communication list.
For details about connection forwarding settings, see the SteelHead Interceptor User’s Guide.
Path labels
Specify a unique name for the path label.
Path labels must use characters that are alphanumeric, underscore, hyphen, or spaces.
Interceptor labels <path>
Specify a unique name for each selected Interceptor.
7. Click Apply & Continue to display the Add SteelHeads page.
8. Select the SteelHeads you want to add to the cluster and click Next to display the SteelHeads Labels page.
9. Specify a unique label for each SteelHead and Apply & Continue to display the Summary page.
10. Click Show Cluster Summary to review a summary of your configuration settings.
11. Optionally, click the links on the Summary page to configure in-path and load-balancing rules.
12. Click Close to close the wizard. The cluster is displayed in the clusters table.
