Configuring IPv4 ACLs
Command
Step 3 deny {source [source-wildcard] | host source |
any}
or
permit {source [source-wildcard] | host source
| any}
Step 4 end
Step 5 show access-lists [number | name]
Step 6
copy running-config startup-config
To remove a named standard ACL, use the no ip access-list standard name global configuration
command.
Beginning in privileged EXEC mode, follow these steps to create an extended ACL using names:
Command
Step 1
configure terminal
Step 2 ip access-list extended name
Step 3 {deny | permit} protocol {source
[source-wildcard] | host source | any}
{destination [destination-wildcard] | host
destination | any} [precedence precedence]
[tos tos] [established] [time-range
time-range-name]
Step 4 end
Step 5
show access-lists [number | name]
Step 6 copy running-config startup-config
To remove a named extended ACL, use the no ip access-list extended name global configuration
command.
When you are creating standard extended ACLs, remember that, by default, the end of the ACL contains
an implicit deny statement for everything if it did not find a match before reaching the end. For standard
ACLs, if you omit the mask from an associated IP host address access list specification, 0.0.0.0 is
assumed to be the mask.
