64 Switch Features
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 543.
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 543.
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 791.
