  • Support for Flexible Ethernet services (QFX10002, QFX10008, and QFX10016)—Starting in Junos OS Release 22.3R1, you can configure Flexible Ethernet services encapsulation on the QFX10000 line of switches. This configuration ensures that the switches support multiple logical interfaces on the same physical interface mapped to the same bridge domain.


    The QFX10002-60C switches do not support this feature.

  • Support for 128 Down-Link Interfaces during Uplink Failure Detection (QFX5120-32C and QFX5120-48Y)—Starting in Junos OS Release 22.3R1, the number of down-link interfaces supported during the Uplink Failure Detection is increased from 48 down-link interfaces to 128 down-link interfaces.
