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.
