AT-8000GS/48 
| Layer 2 Stackable Gigabit Ethernet Switch
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.
