Configuring the WSM using Device Manager

Configuring WTLS health checks

The WSM performs a WTLS Hello-based health check for connection-oriented WTLS traffic on port 9203. It sends a new WTLS Client Hello to the WAP gateway, and checks to see if it receives a valid WTLS Server Hello back from the WAP Gateway. You can configure a WTLS health check on the real server group, and you can change the port on which your gateway listens to WTLS traffic.

To configure WTLS health checks for a real server group, see Configuring a health check for a real server group.

To change the port on which your gateway is listening to WTLS traffic:

1. From the device view, select the Web Switching Module.

The Web Switching Module is highlighted.

2. From the Edit menu, choose WSM Card > L4 Switching> WAP.

The WAP dialog box opens to the General tab.

3. In the WTLS Port to Health Check field, type a port number (9203 is the default) on which WTLS health checks are performed.
4. Click Set > Apply.

An Information dialog box opens reminding you to save the configuration.

5. Click OK.

The Information dialog box closes.

6. From the General tab, click Close.

The WTLS port is configured.

7. To save the change, right-click the WSM card and choose one of the following from the shortcut menu:
• Save configuration (backup)--Saves changes to the active and backup WSM configuration blocks.
• Save configuration (no backup)--Saves changes to the active WSM configuration block.
