    ****************************************************************
    The load balancer may not save the crossport affinity
    to a configuration file or it may be saved incorrectly.
    

Problem conclusion

  • The crossport affinity port attribute must be defined when the
    port is added to the load balanacer and the port defined for
    crossport affinity must already be defined.
    
    -Crossport setting is not saved with the selection algorithm
    "conn+affin".
    -When the attribute is saved, it is saved on both ports
    leading to a syntax error when the saved configuration is
    loaded.
    -Saved as a "port set" command when the stickybits port
    attribute is also set which causes a syntax error when the
    saved configuration is loaded.
    
    Code has been corrected to save crossport correctly.
    
    Fix levels:
       8.5.5.19
       9.0.5.6
    

Temporary fix

  • Edit the load balancer configuration and correct the commands
    when necessary.
    Example:
    dscontrol port add <cluster>@<port1> selectionalgorithm
    conn+affin stickytime 300
    dscontrol port add <cluster>@<port2> selectionalgorithm
    conn+affin stickytime 300 crossport <port1>
