Usage Guidelines
•
The DNS strings configured with this command are added to the list of the pre-defined DNS strings, as
shown above. Note that the pre-defined strings are not configurable and will always remain on the list.
•
Use the no form of this command to remove all the user-defined keywords from the DNS keyword list.
•
Any DNS packets received that do not contain the specified DNS strings (pre-defined or user-defined)
are dropped.
•
Up to four keywords are configurable. Each time this command is used, the user-defined keyword
strings are overwritten with the new strings. For example, if the DNS string list contains four user-
defined strings, the next time this command is used and only two strings are specified, the four exist-
ing strings are removed and only the two new strings are added to the list.
