What's Changed in Release 22.2R2

Starting in Junos OS Evolved Releases 22.1R3, 22.2R2, and 22.3R1, QFX5130 switches don't copy the Type of Service (ToS) field when encapsulating a VXLAN packet by default. You can enable copying the ToS field upon VXLAN encapsulation using the vxlan-tos-copy-filter statement at the edit forwarding-options hierarchy. This statement copies both the DSCP and ECN values in the ToS field from the IP header of a packet to the outer IP header of the VXLAN packet.

AR replicators with OISM install multicast states only on the OISM SBD (QFX5130-32CD and QFX5700)—In an EVPN-VXLAN ERB fabric with many VLANs, QFX5130-32CD and QFX5700 switches running as assisted replication (AR) replicators with optimized intersubnet multicast (OISM) might have scaling issues when they install multicast (*,G) states (with IGMPv2) or (S,G) states (with IGMPv3). As a result, these switches only install these multicast states on the OISM supplemental bridge domain (SBD) VLAN. They don't install these states on all OISM revenue bridge domain VLANs. On those devices, you see multicast group routes only on the SBD in show multicast snooping route command output.

sFlow configuration? sFlow configuration is allowed only on et, xe, and ge interfaces in EVO-based platforms. All other interfaces are blocked for configuring sFlow on EVO platforms. A cli error will be thrown if sFlow is configured on any other interface other than et, xe or ge interface.

Deprecated functions in the libpyvrf Python module (ACX Series, PTX Series, and QFX Series)—The libpyvrfPython module no longer supports the get_task_vrf() and set_task_vrf() functions.

Support for temperature sensor (PTX10001-36MR)—We support the temperature sensor statement at the edit chassis cb hierarchy level. You can use the temperature sensor statement to increase the fan speed and customize the temperature threshold. We recommend certain values for ZR and ZR-M modules to work which helps the temperature to remain within the thresholds.
