Descriptions
The SNMP Poll Reports collect data by issuing up to three SNMP poll requests to
each candidate DHCT. The term candidate DHCTs refers to DHCTs in the DNCS
database that have an associated MAC address, IP address, QPSK Modulator, and
QPSK Demodulator, along with an administrative status of In Service-Two Way. If a
DHCT listed in the DNCS database does not meet all of these criteria, it will be
excluded from the SNMP Poll Report. The SNMP poll request determines the
current two-way communication ability of each DHCT.

When the SNMP Poll Report is run, each candidate DHCT is polled (this is also
called an SNMP "get" request). This SNMP poll collects all of the data necessary for

into the data collected.
If a DHCT does not respond to the initial SNMP poll, it is polled up to two more
times (for a maximum of three attempts). If the SNMP poll is unsuccessful after three
attempts, the DHCT is considered to be a non-responder and will appear only on the
Non-Responding DHCTs-SNMP Poll Report. However, if at least one of the three
SNMP poll attempts succeeds, then the DHCT will appear in the OS/App Version,
Memory, and DHCT Uptime Reports.
