The first rule that matches the traffic stops further processing of the frames. • Standard ACLs and extended ACLs cannot have the same name. ACL configuration and management You need to enter either the copy running-config startup-config command or the write memory command to save your configuration changes to Flash so that they are not lost if there is a system reload or power outage.

Creating a standard MAC ACL and adding rules NOTE You can use the resequence command to change all the sequence numbers assigned to the rules in a MAC ACL. For detailed information, see "Reordering the sequence numbers in a MAC ACL" on page 90. To create a standard MAC ACL and add rules, perform the following steps from Privileged EXEC mode. 1. Enter the configure terminal command to access global configuration mode. 2. Create a standard MAC ACL and enter ACL configuration mode. 88 Dell Converged Enhanced Ethernet Administrator's Guide 53-1002116-01
