Configure Access Control Lists
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. Switch
software supports IPv4 and MAC ACLs.
To configure an ACL, first create an IPv4-based or MAC-based ACL ID. Then, create a rule
and assign it to a unique ACL ID. Next, define the rules, which can identify protocols, source,
and destination IP and MAC addresses, and other packet-matching criteria. Finally, use the
ID number to assign the ACL to a port or to a LAG.
To view ACL configuration examples, see Access Control Lists on page 340.
