Prestige 681 SDSL Router
Filter Configuration
9-7
To speed up filtering, all rules in a filter set must be of the same class, i.e., protocol filters or generic filters.
The class of a filter set is determined by the first rule that you create. When applying the filter sets to a
port, separate menu fields are provided for protocol and device filter sets. If you include a protocol filter set
in a device filters field or vice versa, the Prestige will warn you and will not allow you to save.
