426 Configuring Quality of Service

•
Minimum Delay
— The queue is assigned to a strict priority policy, and traffic is assigned to
the highest priority queue.
•
Ingress Metering/Rate Limiting
— A maximum bandwidth value is specified beyond which
all traffic is dropped. This is done by setting a meter at the input for the maximum
bandwidth, and setting the excess policy to drop. In order to effectively configure this service,
the total bandwidth on a specific egress port cannot exceed the port rate.
