ACL Configuration
Use these commands to create Access Control Lists (ACLs).
ACL Overview
ACLs define matching criteria used for IP filtering and Quality of Service functions. An
Access Control List (ACL) filters network traffic by controlling whether packets are forwarded
or blocked at the switch interfaces. You use ACLs to block IP packets from being forwarded.
The switch examines each packet to determine whether to forward or drop the packet, based on
the criteria specified in each ACL. ACL criteria can be the traffic source or destination address,
the upper-layer protocol, or other information.
