I have a network with 1000 devices in monitoring with snmpcollector and snmpv 2 and 3.
There are 40 devices that it's not possible discovery from snmpcollector. I see that these devices response to ping. For example...
Pinging 10.200.15.193 with 32 bytes of data:

Ping statistics for 10.200.15.193:
Packets: Sent = 4, Received = 4, Lost = 0 (0% loss),
Approximate round trip times in milli-seconds:
Minimum = 1926ms, Maximum = 2280ms, Average = 2127msThe are snmp credentials are working.
But SNMPCOLLECTOR indicate this message on this 40 devices...
Discovery Failed - Discovery of device BOG_MED_STO386.local.com.co exceeded the configured timeout of 15 minutes
I try testing change the SNMP Timeout in Milliseconds = 5000 with SNMP Retries = 3, another configuration SNMP Timeout in Milliseconds = 10000 with SNMP Retries = 2, in other device with SNMP Timeout in Milliseconds = 30000 with SNMP Retries = 2 but not work. For example...
Why happen this?
What I need configure in snmpcollector for this working?
Maybe it's a problem of OS for this 40 devices?
The devices are Cisco 1905k 9, Cisco 1721, Cisco Cat 295024
