Found the problem... This KVM seems to refuse SNMPv2 commands.
I modified snmp-config.xml to force a downgrade to SNMPv1 for this single IP and it resumed working normally.
Hope this will help someone else!

Took me a little while to get net-snmp to compile snmpwalk on Cygwin but I got it.
> snmpwalk -c [comm] -v 2c [target] system
Timeout: No Response from [target]
Using SNMPUTIL.exe
Variable = system.sysDescr.0
Value = String 2161DS 03.01.00
Variable = system.sysObjectID.0
Value = ObjectID 1.3.6.1.4.1.10418.3.1.8
Variable = system.sysUpTime.0
Value = TimeTicks 26026100
Variable = system.sysContact.0
Value = String [...]
Variable = system.sysName.0
Value = String [...]
Variable = system.sysLocation.0
Value = String [...]
Variable = system.sysServices.0
Value = Integer32 72

Can you walk the system, interfaces, ifx, and ip tables independently?
snmpwalk -c public -v 2c <hostname> system
snmpwalk -c public -v 2c <hostname> interfaces
snmpwalk -c public -v 2c <hostname> ip
snmpwalk -c public -v 2c <hostname> ifx
(FW version for the KVM: 2161DS 03.01.00)
Hello,
All I can get to prove a DELL/Avocent KVM is a "timeout" regardless of the time I give it to complete. SNMP-walking the whole set (on 1.6.3.1.2.1 for example) takes a fraction of a second by hand.
All I can see in the logs (including turning to DEBUG output) is:
Timeout retrieving SnmpCollectors for X.X.X.X
The firmware is rather old. The traps are working correctly, I just can't collect in read-mode. Is this device famously failing to implement a standard SNMP agent?
Regards,
Julien
