IPv4 Access Control Lists (ACLs) Editing ACLs and Creating an ACL Offline • To create a new ACL, just open a text file in the appropriate directory on a TFTP server accessible to the switch. 2. Use the text editor to create or edit the ACL(s). 3. Use copy tftp command-file to download the file as a list of commands to the switch. Creating an ACL Offline Use a text editor that allows you to create an ASCII text file (.txt). If you are replacing an ACL on the switch with a new ACL that uses the same number or name syntax, begin the command file with a "no" command to remove the earlier version of the ACL from the switch's running-config file. Otherwise, the switch will append the new ACEs in the ACL you download to the existing ACL. For example, if you plan to use the copy command to replace ACL "103", you would place this command at the beginning of the edited file: no ip access-list extended 103 Removes an existing ACL and replaces it with a new version with the same identity. no ip access-list extended 103 ip access-list extended "103" To append new ACEs to the ACL instead of replacing it, you would omit the first line. deny tcp 0.0.0.0 255.255.255.255 10.10.10.2 0.0.0.0 eq 23 log permit ip 0.0.0.0 255.255.255.255 0.0.0.0 255.255.255.255 exit Figure 9-26. Example of an Offline ACL File Designed To Replace An Existing ACL For example, suppose that you wanted to create an extended ACL to fulfill the following requirements (Assume a subnet mask of 255.255.255.0.): ■ ID: 160 ■ Deny Telnet access to a server at 10.10.10.100 from these three IP addresses on port 2 (with ACL logging): • 10.10.20.17 • 10.10.20.23 • 10.10.20.40 ■ Allow any inbound access from all other addresses on port 2: 9-65
