For all JUNOS platform, the interfaces statistics are not clearing via snmp after they are clear from the cli. Please take a look to the following outputs, Topology: Mx480(ge-5/2/0.0).1 --------------.2 (ge3/0/1.0)m120 - Addressing: 10.10.10/30 OID: … [Read more...]
How to generate spoof SNMP traps for testing trap receiver
This article will explain how a spoof SNMP trap can generate to verify that the traps are being received at the trap viewer after configuration of the traps. Traps are only generate when there is an event on the chassis. In an initial configuration or when there is change in the target knob for sending the traps there will be a need to test and see how the traps are being … [Read more...]

The community syntax for SNMP polling of the logical-router (Logical Systems)
Information about the community syntax for SNMP polling of the logical-router. When a logical system is created, a default routing instance (known as default) is always created within the logical system. This name should be used, when querying SNMP data for the logical-system (Logical-System-name/default@community). For example, in a lab scenario,SNMP can be configured … [Read more...]
SNMP counters (ifInOctets, ifOutOctets, ifHCInOctets and ifHCOutOctets) do not count the Ethernet Header (14 bytes)
This article describes the issue of the SNMP counters (ifInOctets, ifOutOctets, ifHCInOctets, and ifHCOutOctets) not counting the Ethernet Header (14 bytes). As per RFC 2665, the four OID's (ifInOctets, ifOutOctets, ifHCInOctets, and ifHCOutOctets) should be adding the framing characters for the interface. However, in Juniper's implementation, the traffic statistics that are … [Read more...]

This message indicates that the device has corrected a condition in which it would have flooded an IGMP packet with an unknown type field back out the same port on which it was received. This message is cosmetic. Example of log messages generated: May 24 19:47:08 … [Read more...]
