With Cisco IOS version 11.2, Cisco introduced the Named ACLs. Named ACLs are Standard or Extended ACLs which are give names instead of a ACL number. Technically, other than giving a name to the ACL there isn't any other difference when it comes to the functionality as in Standard or Extended ACL.
To add a Named ACL,
ciscorouter# conf term
ciscorouter(config)# ip access-list standard ACL-IN
ciscorouter(config-std-nacl)#
where ACL-IN is the ACL name given to the Standard ACL. Click here for configuring Standard Access Lists.
ciscorouter(config)# ip access-list extended ACL-OUT
ciscorouter(config-ext-nacl)#
where ACL-OUT is the ACL name given to the Extended ACL. Click here for configuring Extended Access Lists
To apply the ACL onto an interface
ciscorouter# conf term
ciscorouter(config) int fa0/0
ciscorouter(config-if)# ip access-group ACL-OUT out
Here, we apply the ACL-OUT named ACL to the FastEthernet0/0 interface.
