Obtaining CMTS and DPS Connection Status

Using an SNMP GetNext request, you can obtain connection status information from the following Tables:

cmtsConnTable for cable modem termination systems (CMTSs)

dpsConnTable for downstream policy servers (DPSs)

The following information is reported for each network element of both kinds of devices:

ID
Host Name
Connection Type
Connection Status
Last Connection Time
Last Disconnection Time
Collection Time Stamp

Counters are updated every thirty seconds.

You can obtain this data using a variety of SNMP applications. The example shown in Figure 1 uses snmpwalk.
