Using SNMP to Retrieve Information from Devices Running Junos OS and Other Network Devices
You can use SNMP to retrieve information from a router running Junos OS or a network device. For example, if you create a router initialization script that uses SNMP, you need to specify the SNMP communities that are on the router.
We recommend that you specify SNMP communities for each virtual router. You can also configure global default SNMP communities.
You can configure global default SNMP communities that are used if a VR does not exist on the router or if the community strings have not been configured for the VR.
To configure global default SNMP communities:
Click Configure, expand Shared>SAE>Configuration>Driver, and then click SNMP.
The SNMP pane appears.
Click Create, enter information as described in the Help text in the main pane, and then click Apply.
