Specifying User-Defined Criteria
The Edit Priority/Outbound Filters window and Edit Priority/Outbound Template
window provide a User-Defined criterion option.The User-Defined option allows
you to set up a user-defined criterion based on bit patterns in the packet’s data link
or IP header that are not supported in predefined criteria.
Adding user-defined criteria is similar to adding predefined criteria, except you
must specify the criterion’s location in the packet. (With predefined criteria, the
locations are established.)
See Chapter 4 for the supported IP and data link header reference points you can
use to specify user-defined criteria for outbound traffic filters.
