I'm reading Wendell Odom's and Michael J. Cavanaugh's "Cisco DQoS Exam
Certification Guide," ISBN 1-58720-058-9, in an effort to better-understand
shaping, policing, marking, congestion management, congestion avoidance,
etc.
I'm having trouble understanding the term "input," or even "in," when
applied to an edge router's ISP-facing interface.
If, for example, I configure a class-based policy and apply it with the
service input command on the interface, does the policy not apply to traffic
coming into the interface from the ISP? What happens if that same policy is
misconfigured with "service output" instead?
