Configuring service groups in the Content Gateway manager

Every WCCP service group that redirects traffic to a Content Gateway proxy must have a corresponding service group defined for it in the Content Gateway server or cluster.

To define service groups:

Go to the Configure > Networking > WCCP page.

Review the existing entries in the Service Groups table and click Edit File to add, modify, delete, or reorder service groups.

Entries are stored in the wccp.config file.

Click Refresh to prompt the Content Gateway manager to reread the wccp.config file and update the table.

Detailed instructions can be found in Configuring a service group (editing wccp.config).

If Content Gateway is configured in a cluster, under Synchronize in the Cluster, Select Enabled (default) or Disabled. (The value of this option is always synchronized in the cluster.)

When this option is enabled, the WCCP configuration (stored in wccp.config) is synchronized in the cluster and configuration changes can be made on any node in the cluster.

When this option is disabled, the WCCP configuration is not synchronized in the cluster and changes to the WCCP configuration must be made individually on each node. A common use case for this is to control which service groups are enabled/disabled on each node, and/or to use proportional load distribution using weight.

If this option is disabled, and then later enabled, the configuration on the node on which the administrator enables the option is used to initially synchronize the cluster.

Caution: When Synchronize in the Cluster is disabled, you must visit each node in the cluster to examine and maintain your WCCP configuration. This can also make WCCP troubleshooting more difficult.
