Important Notes:

  • See sk101539 for information about the support of ClusterXL in Load Sharing mode for the IPSec VPN Software Blade (supported starting in R81.10).
  • On R80.20 and R80.30, you must install the required Jumbo Hotfix Accumulator on each cluster member and on the Management Server that manages this cluster.
  • In versions R80.20, R80.30, and R80.40, you must permanently set the value of the kernel parameter ccl_force_sticky parameter to 1 on all cluster members (starting in R81, this parameter is not applicable - its value must remain 0).
    The default value of this kernel parameter is 1 in:
    • R80.40 Jumbo Hotfix Accumulator Take 26 and higher
    • R80.30 Jumbo Hotfix Accumulator Take 169 and higher
    • R80.20 Jumbo Hotfix Accumulator Take 146 and higher

  2. Configure the required environment variable on the Management Server:

        vi $FWDIR/scripts/cpm.sh
      • On a Multi-Domain Security Management Server:
        vi $MDS_FWDIR/scripts/cpm.sh
    2. Go to the end of the file and find the last line:
      exec $JAVA_HOME/bin/java ...
    3. Above that last line add this new line:
      export ENABLE_CLUSTER_LOAD_SHARING_R80_20=1
    4. Save the changes in the script and exit the editor
