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.)
