What's Changed
Learn about what changed in this release for QFX Series switches.
EVPN
-
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 theedit 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.
General Routing
-
Two new alarms are added and can be seen with MPC11E when 400G-ZR optics are used. High Power Optics Too Warm: warning of the increase in chassis ambient temperature with no functional action taken on the optics Temperature too high for optics power on: New inserted optics when the chassis ambient temperature is elevated beyond the threshold will not be powered on and would need to be reinserted when the ambient temperature is within the acceptable range
Juniper Extension Toolkit (JET)
-
Python 3 is the default and only Python version for executing Juniper Extension Toolkit Python scripts (ACX Series, PTX Series, and QFX Series)—Junos OS Evolved supports only Python 3 for executing Juniper Extension Toolkit (JET) scripts written in Python. Python 2.7 is no longer supported for executing JET scripts, and we've deprecated the
language python
statement at the[edit system scripts]
hierarchy level.[See Understanding Python Automation Scripts for Junos Devices.]
Junos OS API and Scripting
-
Deprecated functions in the
libpyvrf
Python module (ACX Series, PTX Series, and QFX Series)—Thelibpyvrf
Python module no longer supports theget_task_vrf()
andset_task_vrf()
functions.[See How to Specify the Routing Instance in Python 3 Applications on Devices Running Junos OS Evolved.]
-
Python 3 is the default and only Python version for executing commit, event, op, and SNMP Python scripts (ACX Series, PTX Series, and QFX Series)—Junos OS Evolved supports only Python 3 for executing commit, event, op, and SNMP scripts written in Python. Python 2.7 is no longer supported for executing these types of scripts, and we've deprecated the
language python
statement at the[edit system scripts]
hierarchy level.[See Understanding Python Automation Scripts for Junos Devices.]
Junos XML API and Scripting
-
Ability to commit
extension-service file
configuration when application file is unavailable—When you set theoptional
option at theedit system extension extension-service application file file-name
hierarchy level, the operating system can commit the configuration even if the file is not available at the /var/db/scripts/jet file path.[See file (JET).]
-
Ability to restart restart daemonized applications—Use the
request extension-service restart-daemonize-app application-name
command to restart a daemonized application running on a Junos device. Restarting the application can assist you with debugging and troubleshooting.
Network Management and Monitoring
-
Python 3 is the default and only Python version for executing YANG action and translation Python scripts (ACX Series, PTX Series, and QFX Series)—Junos OS Evolved supports only Python 3 for executing YANG action and translation scripts written in Python. Python 2.7 is no longer supported for executing YANG action and translation scripts, and we've deprecated the
language python
statement at the[edit system scripts]
hierarchy level.[See Understanding Python Automation Scripts for Junos Devices.]
System Management
