Hi,
  Command used for querying the agent is

Tried with another user

snmpwalk -v 3 -u alphionuser -A XXXXXX -a MD5 -l authpriv -x AES -X XXXXXXX <IP 
address> 1.0.8802.1.1.2.1.1.2.0
iso.0.8802.1.1.2.1.1.2.0 = No Such Object available on this agent at this OID

The directive in the snmpd.conf file is

group alp1group usm alphion1user


view   myiso   included        
.1                                                   
view    all          included        
.1.3.6.1.4.1.8742                              
view    all          included         iso.3


access alp1group ""      usm       noauth    exact all all 
all                                         
access alp2group ""      usm       auth    exact all all 
all                                           
access alp3group ""      usm       auth    exact all all 
all                                           



Regards,

OK - so requests authenticated via the group "grpalphionuser"
will be using the internal view '_all_'  which has access to the
whole OID tree (including OIDs starting .1.0....)
   While requests authenticated via the groupss "alp[1-7]group"
will be using the view named "all",  which only has access to
OIDs starting with .1.3.....


What is the command that you are using to try and query the agent?
(i.e. the .1.0.8802.... queries)

What directives do you have in the snmpd.conf that relate to the
community or SNMPv3 user that's specified in this command?

What directives do you have in the snmpd.conf file that relate
to "alphion" or "alphionuser" ?

What happens if you query the agent (for .1.0.8802...) using
these authentication parameters?
