This article explains the meaning of the following SNMP OIDs:

• 1.3.6.1.4.1.2636.3.63.1.0.5
• 1.0.8802.1.1.2.0.0.1

Periodic SNMP traps from switch with the following OIDs in the snmpTrapOID field is seen with the corresponding notification message on the NMS: 

1.3.6.1.4.1.2636.3.63.1.0.5 - This trap is associated with VRRP (Virtual Router Redundancy Protocol) and contains event-specific information.

1.0.8802.1.1.2.0.0.1 - This trap corresponds to LLDP (Link Layer Discovery Protocol) events.

• The SNMP OID 1.3.6.1.4.1.2636.3.63.1.0.5 (jnxLicenseInfringeSingle) indicates an SNMP trap that is generated when the license for a feature is not valid i.e. either expired or not available. In this case, it was VRRP and hence it was called out on the NMS

• The SNMP OID 1.0.8802.1.1.2.0.0.1 (lldpRemTablesChange) indicates an LLDP trap. This is sent when there is a change in the LLDP neighbours of the device that sent the trap. This gives a visibility on topology changes and can be used to send data for visual analysis

Note - lldpRemTablesChange notifications are throttled by the agent to control the resources consumed in sending these traps to the NMS . An NMS should periodically check the value of lldpStatsRemTableLastChangeTime to detect any missed lldpRemTablesChange notification-events, e.g. due to throttling or transmission loss.
