What's Changed
Learn about what changed in this release for QFX Series Switches.
General Routing
-
Before this change most list were ordered by the sequence in which the user configured the list items, for example a series of static routes. After this change the list order is determined by the system with items displayed in numerical sequence rather than by the order in which the items were configured. There is no functional impact to this change.
-
Deprecated license revoke information?Starting in Junos OS Release 23.4R1, we've deprecated the show system license revoked-info command. You can use the show system license and show system license usage commands to know the license information.
-
NOTE: In the CLI using the command request chassis feb slot slot-number offline if you make the primary FEB offline, a traffic loss warning message is displayed and the FEB offline request is rejected. If offline/restart is still intended for primary FEB, use force option in addition to the command. WARNING message displayed in the CLI: "warning: RCB and FEB work in the paired slot mode. FEB %s offline/restart will result in traffic loss and does not cause a switchover. Please re-try after initiating a mastership switchover using 'request chassis routing-engine master switch' CLI. If offline/restart is still intended, use 'force' option in addition to this CLI."
EVPN
- Default behavior changes and new options for the easy EVPN LAG configuration (EZ-LAG)
feature—The easy EVPN LAG configuration feature now uses some new default or derived
values, as follows:
-
Peer PE device
peer-id
value can only be 1 or 2. -
You are required to configure the loopback subnet addresses for each peer PE device using the new
loopback-subnet peer1-subnet
andloopback peer2-subnet
options at theedit services evpn device-attribute
hierarchy level. The commit script uses these values for each peer PE device's loopback subnet instead of deriving those values on each PE device. Theloopback-subnet
option at theedit services evpn device-attribute
hierarchy level has been deprecated. -
If you configure the
no-policy-and-routing-options-config
option, you must configure a policy statement called EXPORT-LO0 that the default underlay configuration requires, or configure the newno-underlay-config
option and include your own underlay configuration. -
The commit script generates "notice" messages instead of "error" messages for configuration errors so you can better handle
edit services evpn
configuration issues. -
The commit script includes the element names you configure (such as IRB instance names and server names) in description statements in the generated configuration.
This feature also now includes a few new options so you have more flexibility to customize the generated configuration:
-
no-underlay-config
at theedit services evpn
hierarchy level—To provide your own underlay peering configuration. -
mtu overlay-mtu
andmtu underlay-mtu
options at theedit services evpn global-parameters
hierarchy level—To change the default assigned MTU size for underlay or overlay packets.

Change in options and generated configuration for the EZ-LAG configuration IRB subnet-address statement—With the EZ-LAG
subnet-address inet
orsubnet-address inet6
options at theedit services evpn evpn-vxlan irb irb-instance hierarchy
, you can now specify multiple IRB subnet addresses in a single statement using the list syntaxaddr1 addr2 ?
. Also, in the generated configuration for IRB interfaces, the commit script now includes defaultrouter-advertisement
statements at theedit protocols
hierarchy level for that IRB interface.
Interfaces and Chassis
-
Starting in Junos OS release 23.2R1, the output of
show chassis power
command displays the state of the power supply in PTX10003 and QFX10003 platforms.[See show chassis power.]
Junos XML API and Scripting
-
XML output tags changed for
request-commit-server-pause
andrequest-commit-server-start
(ACX Series, EX Series, MX Series, QFX Series, SRX Series, and vSRX)—We've changed the XML output for therequest system commit server pause
command (request-commit-server-pause
RPC) and therequest system commit server start
command (request-commit-server-start
RPC). The root element is<commit-server-operation>
instead of<commit-server-information>
, and the<output>
tag is renamed to<message>
.
Network Management and Monitoring
-
NETCONF
<copy-config>
operations support afile://
URI for copy to file operations (ACX Series, EX Series, MX Series, QFX Series, SRX Series, and vSRX)—The NETCONF<copy-config>
operation supports using afile://
URI when<url>
is the target and specifies the absolute path of a local file.[See <copy-config>.]
-
ephemeral-db-support
statement required to configure MSTP, RSTP, and VSTP in the ephemeral configuration database (ACX Series, EX Series, and QFX Series)—To configure Multiple Spanning Tree Protocol (MSTP), Rapid Spanning Tree Protocol (RSTP), or VLAN Spanning Tree Protocol (VSTP) in the ephemeral configuration database, you must first configure theephemeral-db-support
statement at the[edit protocols layer2-control]
hierarchy level in the static configuration database.[See Enable and Configure Instances of the Ephemeral Configuration Database.]
User Interface and Configuration
-
Viewing files with the
file compare files
command requires users to havemaintenance
permission — Thefile compare files
command in Junos OS and Junos OS Evolved requires a user to have a login class withmaintenance
permission.[See Login Classes Overview.]
