access-list ip

This command adds an IP access list and enters configuration mode for standard or extended IP ACLs. Use the no form to remove the specified ACL.

Syntax

[no] access-list ip {standard extended} acl_name

standard – Specifies an ACL that filters packets based on the source IP address.

extended – Specifies an ACL that filters packets based on the source or destination IP address, and other more specific criteria.

acl_name – Name of the ACL. (Maximum length: 16 characters)

Default Setting

None

Command Mode

Global Configuration

Command Usage

An egress ACL must contain all deny rules.

When you create a new ACL or enter configuration mode for an existing ACL, use the permit or deny command to add new rules to the bottom of the list. To create an ACL, you must add at least one rule to the list.

To remove a rule, use the no permit or no deny command followed by the exact text of a previously configured rule.

An ACL can contain up to 32 rules.
