Overview
General Steps for Implementing ACLs
1. Configure at least one ACL. This creates and stores the ACL(s) in the
switch configuration.
2. Assign an ACL. This applies the ACL to either the inbound or outbound
traffic on a designated VLAN.
3. Enable IP routing. Except for instances where the switch is the destina-
tion, assigned ACLs screen IP traffic only when routing is enabled on the
switch.
Caution Regarding Source routing is enabled by default on the switch and can be used to override
the Use of Source
ACLs. For this reason, if you are using ACLs to enhance network security, the
Routing
recommended action is to disable source routing on the switch. To do so,
execute no ip source-route.
