Chapter 21 Configuring Advanced Connection Features Permitting or Denying Application Types with PISA Integration hostname(config-pmap-c)# deny skype hostname(config-pmap-c)# deny yahoo hostname(config-pmap-c)# deny eDonkey The following example denies all traffic except for Kazaa and eDonkey: hostname(config-pmap-c)# deny all hostname(config-pmap-c)# permit kazaa hostname(config-pmap-c)# permit eDonkey Note For a class map with the permit and deny commands, you cannot also include any inspect commands. Step 4 Activate the policy map on one or more interfaces by entering the following command: hostname(config)# service-policy policymap_name {global | interface interface_name} Where global applies the policy map to all interfaces, and interface applies the policy to one interface. Only one global policy is allowed. You can override the global policy on an interface by applying a service policy to that interface. You can only apply one policy map to each interface. The following is an example configuration for PISA integration: hostname(config)# access-list BAD_APPS extended permit 10.1.1.0 255.255.255.0 10.2.1.0 255.255.255.0 hostname(config)# class-map denied_apps hostname(config-cmap)# description "Apps to be blocked" hostname(config-cmap)# match access-list BAD_APPS hostname(config-cmap)# policy-map denied_apps_policy hostname(config-pmap)# class denied_apps hostname(config-pmap-c)# deny skype hostname(config-pmap-c)# deny yahoo hostname(config-pmap-c)# deny eDonkey hostname(config-pmap-c)# service-policy denied_apps_policy inside Configuring the Switch for PISA/FWSM Integration This section describes how to configure the switch for PISA/FWSM integration and includes the following topics: • PISA Limitations and Restrictions, page 21-7 • Changing the MTU on the Switch to Support Longer Packet Length, page 21-8 • Configuring Classification on the PISA, page 21-8 • Configuring Tagging on the PISA, page 21-8 • Sample Switch Configurations for PISA Integration, page 21-9 PISA Limitations and Restrictions The following limitations and restrictions apply to the PISA: OL-20748-01 Catalyst 6500 Series Switch and Cisco 7600 Series Router Firewall Services Module Configuration Guide using ASDM 21-7
