jnxVpnIfDown traps whenever any physical layer 2 interface or the RVI interface flap on a QFX Series node which is part of Q fabric Setup.
jnxVpnIfDown SNMP Trap are sent every time a physical interface or a RVI interface goes down on a Qfabric.
jnxVpnIfUp SNMP Trap are sent every time a physical interface or a RVI interface comes up on a Qfabric.
Importanly both jnxvpnifdown and jnxvpnifUp traps are accompanied with snmp link down and link up traps.
Here are the OID for there traps :
jnxVpnIfDown = 188.8.131.52.4.1.26184.108.40.206.2
jnxVpnIfUp = 220.127.116.11.4.1.2618.104.22.168.1
As illustrated below when the interface xe-0/0/5 went down on a Qfabric – a trap is generated to report the interfaces link-down situation followed by another trap reporting “jnxvpnifdown”.
