With IPHost Network Monitor you can run simple snmp requests against a Cisco device in your network.
docsDevRole
DOCSIS Device Role
1.3.6.1.2.1.69.1.1.1
Defines the current role of this device. cm(1) is a Cable Modem, cmtsActive(2) is a Cable Modem Termination System that is controlling the system of cable modems, and cmtsBackup(3) is a CMTS that is currently connected but is not controlling the system (not currently used). In general, if this device is a 'cm', its role will not change during operation or between reboots. If the device is a 'cmts' it may change between cmtsActive and cmtsBackup and back again during normal operation. NB: At this time, the DOCSIS standards do not support the concept of a backup CMTS, but cmtsBackup is included for completeness.
