Enable SNMP on the Juniper firewall

• Configuration=>Report Settings=>SNMP
• Create a new SNMP Community. Hosts is the Zabbix server and select the interface you want to monitor
• At the interface level, make sure SNMP is ticked.

On the ZABBIX server

• Make sure SNMP is installed
• Find out the SNMP community string of the item you want to monitor using snmpwalk command => snmpwalk -v 1 x.x.x.x -c CommunityName>/tmp/snmpcommand. -v is the version of snmp, and -c is the community name you’ve specified in Juniper. And this command will write to an output file in /tmp directory.
• Find the OID of the SNMP community string using SNMPGET command. snmpget -v 1 -On x.x.x.x CommunityString -c CommunityName
• Go to http://net-snmp.sourceforge.net/docs/mibs/IF-MIB.txt for Community String explanation.
• Follow the Zabbix Manual 1.6 for the rest of the configuration at the SNMP Agent section
• Just note that in the Configuration of Items, you need these: Units=Bit, Use Multiplier with value 8, and choose Delta(speed per second) for Store Value
