WCCP negotiation issues can occur when the following elements differ between the ProxySG appliance and your WCCP network devices:
Changing the Assignment Type from either Mask to Hash, or vice versa.
Changing the Source IP, Source Port, Destination IP or Destination Port.
Modifying the Primary Hash assignment.
Modifying the Alternate Hash assignment.
Modifying the Assignment Mask value.
WCCP Service-Groups must all use the same
Assignment Type configuration settings must be identical on all devices within the WCCP Service-Group. Any changes to any device in the group will cause that device fail to negotiate to join that service-group.
For example, if you have four ProxySG appliances in a Service-Group and if you change the assignment type from
Hash, you must modify the assignment type on all ProxySG appliances.
If you have a need for multiple assignment types in your WCCP network, create separate WCCP Service-Groups for each Assignment Type.
