group   notConfigGroup   v1              notConfigUser
group   notConfigGroup   v2c             notConfigUser

# Third, create a view for us to let the group have rights to:
#       name           incl/excl     subtree         mask(optional)
view    allview        included      .1

# Finally, grant the group read-only access to the systemview view.

#       group           context sec.model sec.level prefix read    write  notif
access  notConfigGroup  ""      any       noauth    exact  allview none   none

##     group.name sec.model  sec.name
group  MyROGroup  v2c        mynetwork
 
##                context sec.model sec.level prefix    read    write    notif
