SNMP Configuration On Juniper Junos

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.

First of all we need to enable SNMP Server operation on router.

Router(config)# snmp-server

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.

There are three priviledge modes. These are:

– 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.

Router(config)# snmp-server community "istanbul" rw

To configure SNMPv3 use the following one:

Router(config)# snmp-server user gokhan auth sha gokhanpassword priv des password group user

Configuring SNMP contact and location is also best practice in Juniper as all vendors.

Router(config)# snmp-server contact gokhan
Router(config)# snmp-server location istanbul office floor3 departmentABC
