[[Procedure]
Step
Operation
1
Go to the configuration mode.
2
Create an access-list defining the access-list number and
access conditions.
3
Go to the interface configuration mode.
4
Enter into the IP configuration mode.
5
apply the access-list that has been set to the corresponding
interface.
Decide where to apply the access conditions – inbound
packets or outbound packets.
6
Use “Show access-list” command to check if the access-list has
been correctly set.
[Related Commands and Syntax]
Standard IP Access-List: The standard IP address-lists uses only the source IP
address in checking the access conditions.

1.
Creates an access-list.
2.
access-list-number: Any number within 0 to 29, source: Source Network
Address, Source-wildcard: Inverse mask of the source address
3.
Instead a pair of “source” and “source-wildcard,” the user can use a
pair of “any (any address)” and “host (a certain address.)”
4.
Wildcard is the inverse mask. For example, if the user writes
132.1.20.1
255.255.255.0
network in a wildcard form, the network will be
132.1.20.1
0.0.0.255
.
5.
Since the default is the deny value, it is recommended to use “Permit
Any Option” at the last line to permit all packets that do not satisfy
conditions when every condition cannot be considered.
