  • Page 70: Bandwidth (Qos)

    For configured behavior to work correctly, you must ensure that the sum of the bandwidths plus any priority traffic is not greater than the bandwidth of the interface itself. If the interface is oversubscribed, unpredictable behavior results. Modular QoS Command Reference for Cisco NCS 5500 Series and Cisco NCS 540 Series Routers...
