Usage Guidelines
•
Use the no form of the command to remove tcpflags from a condition; however, at least one classifica-
tion parameter must be associated with a condition.
•
Use the any option to indicate that a match on any one of the specified TCP flags qualifies as a match
for the condition. Use the all option to indicate that a match on all specified TCP flags is required to
qualify as a match for the condition.
•
Enter one or more TCP flags after the any or all keyword to indicate that the value of the flag bit must
be set to one to qualify as a match.
•
Enter one or more TCP flags after the mask keyword to indicate which TCP flags to match.
•
If a TCP flag is specified as part of the mask but does not have a corresponding match value specified
with the any or all options, then zero is assumed as the match value. For example, tcpflags all f s
mask f s a looks for the following bit values to determine a match: f=1, s=1, a=0.
•
Typically this condition is used in combination with source ip, destination ip, source port, destina-
tion port, source TCP port, or destination TCP port conditions.
•
Note that even though tcpflags can be used with most action parameters, it is mainly intended for ACL
use.
