HP SIM 7.2 : SNMP and system type identification issue with Xerox Workcentre

[OlivierV]

Hello.

I have a problem with a Xerox WC 7530 I'm trying to identify with HP sim.

I found a SNMP OID that gives the printer type in the mib xerox-general-mib.mib (also known as 07gen.mib) and the OID xcmGenBaseSystem1284DeviceId (1.3.6.1.4.1.253.8.51.1.2.1.20.1). All the xerox mibs are imported into SIM.

Querying this OID with getif or Snmputil works perfectly.

If I use this OID with HP Sim to identify the type, I get a warning : Could not retrieve this object identifier from the target system...

And after that, I'm unable to get anymore SNMP answer from the printer with Getif or snmputil.

And the embedded web interface of the printer displays another warning (translated from french) :

16-586-00 network management error. Power off/on the machine. Printing and other services are available.

I must restart the machine to make SNMP available again.

I don't know how SIM makes the query but it seems not supported by the printer. I can of course use SysDescr from SNMPV2 mib, it works with SIM too, but I would prefer to use an internal value.

I tried to use OIDs 1.3.6.1.4.1.253.8.51.1.2.1.20.1 and 1.3.6.1.4.1.253.8.51.1.2.1.20, same behaviour.

Does one of you have an idea about this issue ?

Regards.
