Understand Alarm Types And Severity Levels On Ex Series Switches - Juniper EX9214 Hardware Manual

Cause
On EX9200 switches, if an IRB logical interface is configured on an EX9200-6QS line card as part of a
VLAN, any device that is connected through that interface is unable to route traffic outside of the
subnet because the EX9200-6QS line card drops all ARP requests. This happens because even though
the minimum Junos OS release that supports the EX9200-6QS line card is Junos OS Release 14.2R1,
this release does not support a configuration that includes an IRB logical interface configured on an
EX9200-6QS line card as part of a VLAN.
Solution
Upgrade Junos OS to the release specified in TSB16659.
