ACL Configuration Process
To configure ACLs, follow these steps:
•
Create a MAC ACL by specifying a name.
•
Create an IP ACL by specifying a number.
•
Add new rules to the ACL.
•
Configure the match criteria for the rules.
•
Apply the ACL to one or more interfaces.
IP ACL CLI Example
The script in this section shows you how to set up an IP ACL with two rules, one applicable to
TCP traffic and one to UDP traffic. The content of the two rules is the same. TCP and UDP
packets will only be accepted by the Unified Switch if the source and destination stations have
IP addresses that fall within the defined sets.
