This article explains how to restrict access to specific OIDs in SNMP.

If you have a requirement with SNMP that specific OIDs need to be excluded from SNMP polling for specific community.

This is specifically useful for security reasons where you want to restrict certain SNMP polling agents to only be able to access certain SNMP OIDs on Junos platforms.
This can be done with the help of SNMP views.

For example, you want a SNMP polling agent 192.168.1.2 to not be able to access the following OID :

We can create a view for this:

root@J2320-2# show snmp
view view-1 {
    oid .1 include;
    oid 1.3.6.1.2.1.1.1 exclude;
}
community public {
    view view-1;
    authorization read-write;
    clients {
        192.168.1.2/32;
    }
}

This view will restrict the access for 192.168.1.2 in such a way that it will not be able to poll the above given OIDs but will be able to poll everything else.
