IP Extended Rules
Use the IP Extended Rules page to define rules for IP-based extended ACLs. The access list 
definition includes rules that specify whether traffic matching the criteria is forwarded 
normally or discarded.
Note: There is an implicit “deny all” rule at the end of an ACL list. This 
means that if an ACL is applied to a packet and if none of the explicit 
rules match, then the final implicit “deny all” rule applies and the 
packet is dropped.
To display the IP extended Rules page, click Security  ACL, then click the Advanced  IP 
Extended Rules link. In the following figure, an extended IP ACL exists, and one rule has 
been configured.
