Along with subnetting and VLSM, access control lists (ACLs) are one of the bugbear subjects for new Cisco students. Among the problems are learning the IOS configuration commands, understanding ACL rules (including the implicit “deny all” rule), and learning the port numbers and protocol types.
Like any subject, you should take the learning process one step at a time, apply every command you see here to a router, and do lots and lots of labs.
Today you will learn about the following:
- ACL basics
- Standard, extended, and named ACLs
- ACL rules
- Wildcard masks
- ACL configuration
- Troubleshooting ACLs
This module maps to the following CCNA syllabus requirements:
ü Describe the types, features, and applications of ACLs
- Standard
- Sequence numbers
- Editing
- Extended
- Named
- Numbered
- Log option
- Configure and verify ACLs in a network environment
