On all Junos OS QFX5000 Series and EX4000 Series platforms, when a high number of VLANs are configured, a specific DHCP packet will cause PFE hogging which will lead to dropping of socket connections.
This issue affects:
Juniper Networks Junos OS on QFX5000 Series and EX4000 Series
This issue does not affect Juniper Networks Junos OS versions prior to 21.1R1
