4. Apply rules to the new ACL. INTERFACE mode ip access-list [standard | extended] name To view which IP ACL is applied to an interface, use the show config command in INTERFACE mode, or use the show running-config command in EXEC mode. Example of Viewing ACLs Applied to an Interface Dell(conf-if)#show conf ! interface GigabitEthernet 0/0 ip address 10.2.1.100 255.255.255.0 ip access-group nimule in no shutdown Dell(conf-if)# To filter traffic on Telnet sessions, use only standard ACLs in the access-class command. Counting ACL Hits You can view the number of packets matching the ACL by using the count option when creating ACL entries. 1. Create an ACL that uses rules with the count option. Refer to Configure a Standard IP ACL Filter. 2. Apply the ACL as an inbound or outbound ACL on an interface. Refer to Assign an IP ACL to an Interface. 3. show ip accounting access-list EXEC Privilege mode View the number of packets matching the ACL. Configure Ingress ACLs Ingress ACLs are applied to interfaces and to traffic entering the system. These system-wide ACLs eliminate the need to apply ACLs onto each interface and achieves the same results. By localizing target traffic, it is a simpler implementation. To create an ingress ACL, use the ip access-group command in EXEC Privilege mode. The example shows applying the ACL, rules to the newly created access group, and viewing the access list. Example of Applying ACL Rules to Ingress Traffic and Viewing ACL Configuration To specify ingress, use the in keyword. Begin applying rules to the ACL with the ip access-list extended abcd command. To view the access-list, use the show command. Dell(conf)#interface gige 0/0 Dell(conf-if-gige0/0)#ip access-group abcd in Dell(conf-if-gige0/0)#show config ! gigethernet 0/0 no ip address ip access-group abcd in no shutdown Dell(conf-if-gige0/0)#end Access Control Lists (ACLs) 129
