! Define Network Object Group webserver
hostname(config-network)# object-group network webserver
hostname(config-network)# description Web Servers
hostname(config-network)# network-object host 209.165.201.1
hostname(config-network)# network-object host 209.165.201.2
As shown in Example 6-24, you should reference these network object groups in the access list, thereby
consolidating the deny statements into one single line.
Example 6-24. Using Object Groups in the Access List
Code View:
hostname(config)# access-list 101 deny tcp object-group denyhosts object-group
webserver eq www
hostname(config)# access-list 101 permit ip any any
Use the show object-group [protocol | network | service | icmp-type | id grp_id] command to display a
list of the currently configured object groups.
Modular Policy Framework (MPF)
Firewall software offers an adaptable and scalable modular policy framework to configure Security Appliance
features in a manner similar to Cisco IOS Software QoS CLI (also known as Modular QoS CLI??”MQC). For traffic
flows traversing the firewall, flow-based policies can be established for any administratively defined criteria and
then applied to a set of security services, such as firewall policies, inspection engine policies, Quality of Service
(QoS) policies, and VPN policies, each specified traffic flow providing more granular and flexible inspection
control.
