Switch Features 61
Access Control Lists (ACL)
Access Control Lists (ACLs) ensure that only authorized users have access to 
specific resources while blocking off any unwarranted attempts to reach 
network resources. ACLs are used to provide traffic flow control, restrict 
contents of routing updates, decide which types of traffic are forwarded or 
blocked, and above all provide security for the network. The switch supports 
the following ALC types:
•IPv4 ACLs
•IPv6 ACLs
•MAC ACLs
For all ACL types, you can apply the ACL rule when the packet enters or exits 
the physical port, LAG, or VLAN interface.
For information about configuring ACLs, see "Configuring Access Control 
Lists" on page 539.
Time-Based ACLs
With the Time-based ACL feature, you can define when an ACL is in effect 
and the amount of time it is in effect. 
For information about configuring time-based ACLs, see "Configuring Access 
Control Lists" on page 539.
IP Source Guard (IPSG)
IP source guard (IPSG) is a security feature that filters IP packets based on 
the source ID. The source ID may either be source IP address or a source IP 
address source MAC address pair.
For information about configuring IPSG, see "Snooping and Inspecting 
Traffic" on page 781.
