Sir
Thank you very much for your reply.
I am querying a vendor’s MIB and got this error and I have submit a defect to
them.
But I tried “snmpgetnext” command on the failed OID and it can return the next
OID correctly.
Is the “getnext” command different from “snmpwalk” and “snmpgetnext”
Thanks again for your time.
Best Regards
Yufeng Zhu

Sir
Thanks for your time to read this mail. I have a problem with snmpwalk command.
When I try to walk a tree, it stop when one node has error and returns “no such
instance currently exist at this OID”
The reset of the sub nodes will not be walked. I have tried every options that
I can but it still does not working
Could you please tell me a way to fix this?
My interpretation of your problem is:
'snmpwalk stops when it detects an error in the agent it is querying.'
This would be normal. snmpwalk uses getnext to find the 'next' OID, and then
query it
for its value. If an agent returns 'no such', then snmpwalk has no choice but
to stop
since the 'next' variable was in error, snmpwalk can't know what the 'next' OID
after the 'failed' OID might me!
On the other hand, as Dave asked... 'what MIB/OID is it failing on.
If its an OID provided by net-snmp, someone may be able to fix it.
If its an OID in some other vendor's MIB, then that vendor needs to fix it.
