Classifier-Based Software Configuration
Creating a Traffic Class
3. Enter the exit command to exit the class configuration context.
To display a class configuration, enter the show class < ipv4 | ipv6 >
< classname > command (see Figure 9-7).
To edit a class configuration, re-enter the class configuration context
(class command) and enter new match/ignore statements as follows:
• If you do not enter a sequence number, a new statement is inserted at
the end of the class configuration.
• To remove a match/ignore statement from a class configuration, enter
the no <sequence-number > command or the complete form of the no
match ... or no ignore ... command.
• To resequence the order in which match/ignore statements are listed,
enter the resequence command (see “Resequencing Match/Ignore
Statements” on page 9-23).
• To replace an existing match/ignore statement, enter the no
<sequence-number > command to delete the entry and re-enter a
complete <sequence-number > match ... or <sequence-number > ignore
... command.
When you exit class configuration context, the changes are automatically
saved and applied to existing policy configurations on the switch that use
the class if the policies have not been applied to an interface. If a policy
has already been applied to an interface, the editing changes are not
accepted and an error message is displayed.
Example. Figure 9-3 shows an example of two class configurations:
■ “AdminTraffic” selects the administrative traffic sent to, and received
from, the IPv4 address of an administrator’s PC.
■ “http” selects HTTP traffic sent to TCP ports 80, 443, and 8080, and
excludes HTTP traffic sent to, and received from, TCP port 1214.
