Overview
General Steps for Implementing ACLs
1. Configure one or more ACLs. This creates and stores the ACL(s) in the
switch configuration.
2. Assign an ACL.
IPv4 source routing is enabled by default on the switch and can be used to
override ACLs. For this reason, if you are using ACLs to enhance network
security, the recommended action is to disable source routing on the switch.
To do so, execute no ip source-route.
