Re: Please correct my understanding regarding snmpwalk

Hi!

Just like JMJ wrote, the device that is supposed to answer the request 
has not implemented that specific OID/MIB tree. If you run the walk 
detailed below, you'll see that it jumps directly to .1.3.6.1.4.1.8072.2 
and never dives into .1.3.6.1.4.1.8072.1 since the first OID the SNMP 
agent responds with is not .1 (since it isn't implemented) but .2.someting.

$ snmpbulkwalk -On -v 2c -c public 127.0.0.1 .1.3.6.1.4.1.8072

-On gives you only numeric output so you see the OID numbers. I think 
that'll give you a good idea on this matter.

Btw, snmpbulkwalk is a whole lot faster than snmpwalk on v 2c or higher.

$ snmptranslate .1.3.6.1.4.1.8072.2
