    Hi Luca,

    You could check with wireshark to see what the difference is.

    With a "walk" usually a SNMP client sends "GET" and "GETNEXT", until it received the last oid from the MIB on the SNMP agent, this is also what our driver does, however you can also limit the amount of "GET" it will send, in the browse of the SNMP agent.

    Best regards,
    Mark

    Hi Mark,
    is it possible that the interrogation made by the driver is in V1? it seem that (watching on the device). That device support only V2C and doesn't answer on a V1 snmpwalk.
    Could this be the problem? Is there any way to force Zenon driver to use V2C of SNMP?
