Access Control Lists (ACLs)

Access Control Lists enable inspection of

incoming frames and classify them based on

various criteria. Specific actions can then be

applied to these frames in order to more

effectively manage the network traffic. Typically

ACLs are used as a security mechanism, either

permitting or denying entry (hence the name

Access Control) for frames in a group, but can

also be applied to QoS.

Supported ACL types are:

•

IP ACLs – applicable to IP packet type.

All classification fields are related to IP

packets.

•

MAC ACLs – classification fields are based on

Layer 2 fields.
