  ****************************************************************
  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>
