Descriptions
The SNMP Poll Reports collect data by issuing up to three SNMP poll requests to
each candidate DHCT (set-top).
For DNCS environments, 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/ISDS 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.
For ISDS environments, the term refers to DHCTs in the ISDS database that have
an associated MAC address, and operational status equal to IP_Initialized or
IP_55_1_Initialized, along with an administrative status of In Service-Two Way.
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
generating the four SNMP Poll reports. The SNMP Poll reports are different views
into the data collected.
If a DHCT does not respond to the initial SNMP poll, it is polled up to two more
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.
