Interop for 1G interfaces between EX4100 SKUs and ACX5448/ACX5448-M/D, and MX480 will not work. PR1657766

The EX4100 devices, the MACsec interface statistics of the encrypted or decrypted bytes does not get updated properly after a certain value. PR1658584

The EX4600 devices, Virtual Chassis goes in to the Unstable state for 3 to 7 minutes that causes traffic loss. PR1661349

On EX92XX devices with the EVPN-VXLAN (Ethernet VPN-Virtual Extensible LAN) scenario, the DHCP (Dynamic Host Configuration Protocol) packets from the client get dropped while tunneling to the EVPN-VXLAN. When this happens, the packets does not reach the DHCP server and the host could not get the IP address. PR1662524

A common display behavior across EX platforms appears and this is inline with existing platforms. Further in vty, the following log gets generates for pic 1 ports that does not support AN: tvp_port_resource_set AN cfg not supported on Falcon core port:1/3. PR1666227

On EX4100 devices, delay in the CLI display for PoE commands might be observed when more POE devices with LLDP enabled (Power via MDI) are connected to the switch in a scaled environment with Perpetual POE scenarios. The LLDP PD requested power for all the ports are processed for each of the connected PDs, however the values in CLI display (CLI sync) might be delayed. PR1671311

When system gets rebooted or image gets upgraded, the following log might get generated during shutdown time and it is an harmless log: BCM Error: API bcm_plp_mode_config_set(phy_name, phy_info, speed, intf_type, r_clk, if_mode, aux) at tvp_bcm_mgig_tx_enable_set:616 -> -8

When system comes up again, there will be no functional impact. PR1678440

On a continuous switch reboot trigger and when the switch boots back, sometimes a vmcore process might generate a core file. PR1672731
