RE: Problem to get mac address table from 1920 HP switch

Hi Morten,

Unfortunately, switches are in the lastest version. I'm going to try to modify the pynetsnmp file to include the -Cc option. Do you exactly what is the file I have to modify? My NAV version is 4.3.2.

Thanks for all.

I have problems to get mac address table from switch HP 1920. I only can get one o two mac addresses. If I launch a snmpwalk command to these switches from CLI, I get the next error:

Error: OIDs are not increasing

If i execute the snmpwalk command with -Cc, it works fine. How can I configure in NAV the -Cc option?

You can't.

Although, when using pynetsnmp as the SNMP backend, there is a possibility to add command line parameters like `-Cc` to internal functions, NAV does not provide any option to do so.

As the man page for snmpwalk warns, agents that behave illegally and return OIDs out of order can cause an snmpwalk process to loop indefinitely. You'd be better off upgrading your switch, either software- or hardware-wise.
