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.

Console(config)#access-list ip standard david
