To enable debug logging for PBR, enter the debug ip pbr command. A message will be logged
when a PBR policy is applied, when the action in a class becomes inactive, and when an action
in a class becomes active. See the Management and Configuration Guide for your switch.
NOTE: Policy Based Routing (PBR) is available on the 3800 Series switch and the 5400/8200
series switch which all have v2 or higher modules. Any v1 modules will prevent PBR from functioning.
PBR is not available on the 3500, 3500yl, 6200yl, nor 6600 Series switches.
Modifying classes in a policy
You can modify the classes and class-action statements in a policy configuration without removing
them from the policy:
• To modify the match/ignore statements in a class, enter the class-configuration context with
the command, and make the necessary changes by removing or replacing existing statements.
To display a class configuration, enter the following command as shown in “Resequencing a
class configuration” (page 355):
show class [ ipv4 | ipv6 ] classname
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.
• To modify the class-action statements in a policy, enter the policy-configuration context with
the policy feature-name policy-name command. To display a policy configuration,
enter the following command as shown in “Resequencing a policy configuration” (page 361):
show policy feature-name policy-name
Then do one of the following:
• You can enter a new class-action statement. If you do not enter a sequence number, the
new class-action statement is inserted at the end of the policy configuration.
• To remove a class-action statement from a policy configuration, enter the no
sequence-number command or the complete form of the no class ... action
command.
• To resequence the order in which class-action statements are listed, enter the
resequencecommand.
• To replace an existing class-action statement, enter the no sequence-number command
to delete the entry, and re-enter the following complete command:
class [ ipv4 | ipv6 ] classname
action action-name or default-class action action-name
When exiting the policy-configuration context, the changes are automatically saved and applied
to the policy configuration if the policy has not been applied to an interface. If the policy has
already been applied to an interface, the editing changes are not accepted and an error message
is displayed.
Resequencing classes in a policy
You can use the policy command with the resequence option to reconfigure the number at
which the first class-action statement starts, and reset the interval used to number other class-actions.
Resequencing class-actions is useful when you want to insert a new class-action between two
numbered entries.
