Cisco Cable Spectrum Up Spec Management Hop Priority

1.3.6.1.4.1.9.9.114.1.3.1.1.1

A preference priority for changing the frequency, modulation, or channel width supporting the automatic switching of the modulation scheme when the channel becomes noisy. The default priority is frequency, modulation, and channel width. With the default preference, the frequency is changed if there is a clean band available. If there's no clean band available, the modulation is changed. And if the clean band is still not available, the bandwidth is reduced until an acceptable band is found or a minimum bandwidth of 200KHz.
