This object defines how long the device waits for a response after sending an SNMP message to a target host before assuming the response won't arrive and triggering a retry, applied globally to all configured targets. An admin tunes this based on actual round-trip latency to the management station, since too short a timeout on a slow link causes needless retransmissions while too long a timeout delays detection of a truly lost message. For example, the default of 1500 (hundredths of a second, i.e. 15 seconds) gives the device 15 seconds to hear back before it resends an inform per hwARRetryCount.
