What's Changed in Release 22.2R2

Class of Service (CoS)

For PTX Series devices running Junos OS Evolved, software priority medium-lowmaps to hardware priority medium for normal scheduling mode and low for strict priority scheduling mode.

Change in the help syslog PFE command output—In Junos OS Evolved, the output for help syslog PFE command is fixed to be consistent with Junos OS output on PTX10008 device. ERRMSG tags in EVO are named as SFLOWD_ whereas in Junos they are named as PFE_SFLOW_.
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.

[See How to Specify the Routing Instance in Python 3 Applications on Devices Running Junos OS Evolved.]

Starting with Junos Evolved Release 21.4R3 a CSPF LSP uses a new instance ID when attempting to re-signal a down LSP.

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.
