Cisco 4451-X ISR router is running IOS XE Software version 03.13.00.S. I am trying to run the command "debug ip policy" on the router to verify if the traffics are policy-routed correctly, but I get no output displayed on the router for the debug command. I am connected via a console cable and the logging console is enabled. How do I get the debug outputs to display on the router for monitoring? Thanks.
