Configuring IPv4 ACLs
Beginning in privileged EXEC mode, follow these steps to create a standard ACL using names:
Command
Step 1
configure terminal
Step 2
ip access-list standard name
deny {source [source-wildcard] | host source |
Step 3
any} [log]
or
permit {source [source-wildcard] | host source
| any} [log]
Step 4 end
show access-lists [number | name]
Step 5
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
{deny | permit} protocol {source
Step 3
[source-wildcard] | host source | any}
{destination [destination-wildcard] | host
destination | any} [precedence precedence]
[tos tos] [established] [log] [time-range
time-range-name]
Step 4 end
show access-lists [number | name]
Step 5
Step 6
copy running-config startup-config
To remove a named extended ACL, use the no ip access-list extended name global configuration
command.
