• Lock-and-key ACLs

• Reflexive ACLs

• Router ACLs

• Port ACLs

• Defining ACLs

• Maintaining ACLs

For the CCIE Security exam, you are expected to know the different types of ACLs that are available on Cisco equipment, how to implement them, and how to monitor and troubleshoot them. Don't be surprised ...
