Configure SNMP on Juniper
set snmp location “My home Network”
set snmp contact “giany at x83.net”
set snmp community nMSuser authorization read-only
set snmp community nMSuser clients 10.2.2.1/32
set snmp community nMSuser clients 10.0.9.0/24
[root@box ~]# snmpwalk -v 1 -c ‘nMSuser’ 10.2.2.2 | head

Its a good policy to restrict to only a few clients. If I use snmpwalk from a restricted ip /var/log/security prints:
Aug 1 16:45:59 olive.x83.net snmpd[2658]: SNMPD_AUTH_RESTRICTED_ADDRESS: validate_SNMP_community: request from address 10.1.1.1 not allowed
