ip access-list
This command creates an extended IP ACL (Access Control List) identified by name, consisting of classification fields defined for the IP header of an IPv4 frame. The name parameter is a case-sensitive alphanumeric string from 1 to 31 characters uniquely identifying the IP access list. The rate-limit attribute configures the committed rate and the committed burst size.
If an IP ACL by this name already exists, this command enters IPv4-Access_List config mode to allow updating the existing IP ACL.

Note
The CLI mode changes to IPv4-Access-List Config mode when you successfully execute this command.Format | ip access-list name |
