Did you ever stop and think about just how many options you have for controlling traffic in the data plane on a multilayer Cisco Catalyst switch?

Here is a recap of your options –

• Port ACL (PACL) – this option is for your Layer 2 switchports. You can apply:
  • IP standard or extended ACLs for controlling IP traffic
  • MAC ACLs for controlling non-IP traffic
• Router ACL (RACL) – this options is for your Layer 3 ports on the router. You can apply:
  • IP standard or extended ACLs for controlling IP traffic
• VLAN ACL (VACL) – these are also referred to as VLAN Access Maps. You can apply:
  • IP VLAN maps are for controlling IP traffic
  • MAC VLAN maps are used for controlling non-IP traffic

For most of us – we are well-versed in IP extended and standard access control lists. It is the MAC ACLs of the PACL approach and the VACLs that we need the practice with. I will be sure to publish my CBT Nuggets on this subject on YouTube for all to enjoy.
