IP Access Control List (ACL) Commands
This section describes the commands you use to configure IP ACL settings. IP ACLs ensure
that only authorized users have access to specific resources and block any unwarranted
attempts to reach network resources.
that only authorized users have access to specific resources and block any unwarranted
attempts to reach network resources.
The following rules apply to IP ACLs:
•
Managed switch software does not support IP ACL configuration for IP packet fragments.
•
The maximum number of ACLs you can create is hardware-dependent. The limit applies
to all ACLs, regardless of type.
•
The maximum number of rules per IP ACL is hardware-dependent.
•
Wildcard masking for ACLs operates differently from a subnet mask. A wildcard mask is
in essence the inverse of a subnet mask. With a subnet mask, the mask has ones (1's) in
the bit positions that are used for the network address, and has zeros (0's) for the bit
positions that are not used. In contrast, a wildcard mask has (0’s) in a bit position that
must be checked. A ‘1’ in a bit position of the ACL mask indicates the corresponding bit
can be ignored.

access-list
This command creates an IP access control list (ACL) that is identified by the access list
number, which is 1-99 for standard ACLs or 100-199 for extended ACLs.

Description
<1-99> or <100-199>
Range 1–99 is the access list number for an IP standard ACL.
Range 100–199 is the access list number for an IP extended ACL.
Range 100–199 is the access list number for an IP extended ACL.
{deny | permit}
Specifies whether the IP ACL rule permits or denies an action.
