When you configure a Radware Alteon (formerly Alteon) switch for clustering, direct communication between real servers must be enabled. If direct access mode is not enabled when one of the real servers tries to proxy another real server, the connection fails and times out.
To enable direct communication on the Radware Alteon:
Go to cfg > slb > adv > direct.
Specify e to enable direct access mode.
With some L4 switches, you must configure only the services that you are using. For example, if you configure the SSL service for the L4 switch and you have not configured SSL in Access Manager, then the HTTP service on the L4 switch does not work. If the health check for the SSL service fails, the L4 switch assumes that all the services configured to use the same virtual IP are down.
