Explain what is an ACL ACLs are lists of conditions that are applied to traffic traveling across a router's interface.
What are the advantages of named ACL as compared to standard or extended ACL? Intuitively identify an ACL using an alphanumeric name. Eliminate the limit of 798 simple and 799 extended ACLs provide the ability to modify ACLs without deleting and then reconfiguring them
Write the ACL to deny a specific host Router(config)# access-list 1 deny
Write the ACL command to deny hosts from network Router(config)# access-list 1 deny
Write the ACL command to permit hosts from network Router(config)# access-list 1 permit
Assign access-list 1 to the fastethernet interface FA0/0 Router(config)# interface FA0/0 Router(config-if)# ip access-group 1 in
