IPv4 Access Control Lists (ACLs)
Overview
For more details on ACL planning considerations, refer to “Planning an ACL
Application” on page 9-24.
Caution Regarding
the Use of Source
Routing
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 use the no ip source-route command to disable
source routing on the switch. (If source routing is disabled in the running-
config file, the show running command includes “no ip source-route” in the
running-config file listing.)
