SNMP V3 : Bad Credential Check "Error performing SNMP operation"

Michel Hegeraat

Dears,

I've tried to configure SNMP V3 on some devices using LMS 4 as required by a customer and all appears fine.

Except that I could not use the template in netconfig as my customer desired to use AES rather then DES and there is no dropdown box for the priv encryption algorithm.

After a week the customer tells me all his snmp v3 devices are now failing in the credentail check report.

The message is "Error performing SNMP operation"

I've tested this in my lab using LMS 4 and I can confirm that there is no problem speaking snmp v3 to the devices.

But still LMS claims that there is an issue.

Anyone else having this? Did anyone find a sollution?

I just noticed a thread where Joe says this is expected behavior.

I would be nice if the report could produce a sensible message such as "Failed", "RO OK" or "RO & RW OK"

Shouldn't be that hard to fix this

Cheers,
