When a 100G interface on a QFX5120 is converted to a Virtual Chassis port, the interface stays down as the port is configured as 40G internally. PR1638156

With SFP+-10G-CU3M DAC, link remains up on EX4100-48P devices even though the admin is down on peer.

Class-of-service buffer-size exact configuration is not supported. The respective configured queue will still use the shared-pool. PR1644355

On EX4100 devices, the input pps, bps, and byte counters gets displayed as 0 for some ports while traffic runs without any issues. The interface status gets cleared for 0 to 23 and not cleared for 24 to 47 after interface flaps. PR1657995

On EX4100 devices, the Junos telemetry interface FAN and power supply names do not match with CLI. PR1648739

Incorrect trap is generated after removal of fan0 in FPC4. PR1652388

Interop for 1G interfaces between EX4100 SKUs and ACX5448/ACX5448-M/D will not work. PR1657766

EX4100 MACsec interface statistics of encrypted/decrypted bytes won't be updating properly after a certain value. PR1658584

On EX4600 devices, Virtual-chassis remains in the Unstable state for 3 to 7 minutes, causing traffic loss. PR1661349

On EX4600 devices, memory leakage occurs in the eventd process with the longevity test of back to back GRES. 1645852

Some of interfaces gets zero status in the monitor interface traffic command, when traffic gets sent across all interfaces and applied speed of 100m on all 1g copper ports. The issue occurs when you clear the status for interfaces. PR1661617

On EX2300 and EX3400 devices, high CPU utilization might be observed when more PoE devices (more than 25 PDs) gets connected to the switch. PR1667564

When dot1x enabled access port is member of a secondary pvlan (either community or isolated vlan) by configuration then CLI show dot1x interface detail shows the 'Authenticated Vlan' as primary vlan and 'Authenticated secondary vlan' as configured secondary vlan though client/port is not yet authenticated. Data traffic is still blocked until client is authenticated. This is just an incorrect display and discrepancy with other release. There is no know functional impact. PR1668144
