IP ACLs
The commands in this section configure ACLs based on IP addresses, TCP/UDP

an access list containing the required permit or deny rules, and then bind the access
list to one or more ports.

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.
