# First, map the community name "public" into a "security name"

#       sec.name  source          community
#com2sec notConfigUser  default       public

com2sec SEC_NAME  SERVER_IP       COMM_NAME

####
# Second, map the security name into a group name:

#       groupName      securityModel securityName
#group   notConfigGroup v1           notConfigUser
#group   notConfigGroup v2c           notConfigUser

group   GROUP-NAME v1           SEC_NAME
group   GROUP-NAME v2c           SEC_NAME

####
# Third, create a view for us to let the group have rights to:

# Make at least  snmpwalk -v 1 localhost -c public system fast again.
#       name           incl/excl     subtree         mask(optional)
view    systemview    included   .1.3.6.1.2.1.1
view    systemview    included   .1.3.6.1.2.1.25.1.1

view    all           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  systemview none none

access  GROUP-NAME ""      any       noauth    exact  all none none
