Step 3 To add or edit a Layer 3/4 policy map that sets the actions to take with the class map traffic, enter the
following command:
ciscoasa(config)# policy-map name
ciscoasa(config-pmap)#
The default policy map is called “global_policy.” This policy map includes the default inspections listed
in the “Default Settings and NAT Limitations” section on page 9-4. If you want to modify the default
policy (for example, to add or delete an inspection, or to identify an additional class map for your
actions), then enter global_policy as the name.
Step 4 To identify the class map from Step 1 to which you want to assign an action, enter the following
command:
ciscoasa(config-pmap)# class class_map_name
ciscoasa(config-pmap-c)#
If you are editing the default policy map, it includes the inspection_default class map. You can edit the
actions for this class by entering inspection_default as the name. To add an additional class map to this
policy map, identify a different name. You can combine multiple class maps in the same policy if desired,
so you can create one class map to match certain traffic, and another to match different traffic. However,
if traffic matches a class map that contains an inspection command, and then matches another class map
that also has an inspection command, only the first matching class is used. For example, SNMP matches
the inspection_default class map.To enable SNMP inspection, enable SNMP inspection for the default
