ClusterXL Load Sharing mode is available in R80.20 and above, as follows:
- ClusterXL in Load Sharing mode is not supported with IPSec VPN blade enabled (this limitation does not apply to VSX in VSLS mode)
- Jumbo Hotfix has to be installed both on Security Gateway and Security Management/Multi-Domain Management server.
- Starting from R80.20, the ccl_force_sticky kernel parameter must be set to 1 (in fwkern.conf) on all cluster members.
How to unblock ClusterXL Load Sharing mode on the Security Management:
Client side (Windows):
- Open system properties.
- In Advance tab click on "Environment Variables".
- Change ENABLE_CLUSTER_LOAD_SHARING_R80_20 variable to 1.
- Note: Exactly the same variable is used for versions R80.20 and above.
- Save changes.
- Restart your computer.
Server side (Management):
- Edit the cpm.sh file:
Go to the end of the file and find the last line with exec command: "exec $JAVA_HOME/bin/java ..."
Before that line add: export ENABLE_CLUSTER_LOAD_SHARING_R80_20=1
Save the change of the script
- For Security Management server file location is: $FWDIR/scripts/cpm.sh
- For Multi-Domain Management server file location is: $MDS_FWDIR/scripts/cpm.sh
Note: Both the environment variables, on the Windows client and on the Management server must be set.
