We begin the SNMP configuration with Cisco devices and here, we will continue how to configure a Juniper device for SNMP. In this article we will not mention all the parameters deeply like in the before article. We will check the difference of Juniper JUNOS configuration than Cisco IOS.
Secondly we will define Community String. We will do this with an SNMP community name, a user’s privilege level and an IP access list. As we know from the before article, community the community name is like a password and it is used to authenticate messages sent between an SNMP client and SNMP server. The community name is sent in every packet between them.

– ro : Read-only access to the entire MIB except for SNMP configuration objects.
– rw : Read-write access to the entire MIB except for SNMP configuration objects.
– admin : Read-write access to the entire MIB.
The maximum number of communities in each virtual router is 32. And an SNMP community permits only read-only access by default.
To configure SNMPv3 use the following one:
Configuring SNMP contact and location is also best practice in Juniper as all vendors.
