Available options when displaying information for a single CM
classifiers Displays the classifiers for the modem.
classifiers cache Displays the classifiers in the cache maintained for each CM. (This cache is
based on IP header field values and speeds up classifier lookups and reduces
per packet processing overhead.)
classifiers verbose Displays detailed information for the modem's classifiers.
cpe Displays the CPE devices accessing the cable interface through the CM.
cnr (For Cisco uBR-MC16S only) Displays the upstream carrier/noise ratio (CNR)
for the specified CM (in dB).
