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:

Steps

  1. Go to the Configure > Networking > WCCP page.
  2. 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).
  3. 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.
