What's Changed
Learn about changes in behavior and syntax in this release for QFX Series switches
EVPN
Change in options and generated configuration for the EZ-LAG configuration IRB subnet-address statement—With the EZ-LAG
at thesubnet-address inet
orsubnet-address inet6
or[edit 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.-
Updates to syslog EVPN_DUPLICATE_MAC messages—EVPN_DUPLICATE_MAC messages in the System log (syslog) now contain additional information to help identify the location of a duplicate MAC address in an EVPN network. These messages will include the following in addition to the duplicate MAC address:
- The peer device, if the duplicate MAC address is from a remote VXLAN tunnel endpoint (VTEP).
- The VLAN or virtual network identifier (VNI) value.
- The source interface name for the corresponding local interface or multihoming Ethernet segment identifier (ESI).

: EVPN_DUPLICATE_MAC: MAC address move detected for 00:01:02:03:04:03 within instance=evpn-vxlan on VNI=100 from 10.255.1.4 to ge-0/0/1.0.For more on supported syslog messages, see System Log Explorer.
Infrastructure
-
Option to disable path MTU discovery—Path MTU discovery is enabled by default. To disable it for IPv4 traffic, you can configure the no-path-mtu-discovery statement at the
edit system internet-options
hierarchy level. To reenable it, use the path-mtu-discovery statement.[See Path MTU Discovery.]
Junos OS API and Scripting
-
<get-trace>
RPC support removed (ACX Series, PTX Series, and QFX Series)—Theshow trace application app-name
operational command and equivalent<get-trace>
RPC both emit raw trace data. Because the<get-trace>
RPC does not emit XML data, we've removed support for the<get-trace>
RPC for XML clients. -
XML output tags changed for
request-commit-server-pause
andrequest-commit-server-start
(QFX Series)—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 (QFX Series)—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>.]
-
Device family identifier changed for native YANG modules (QFX Series)—Starting in Junos OS Evolved Release 23.4R2, native YANG modules for QFX Series devices by default use the
junos
device family identifier instead of thejunos-qfx
identifier in the module's name, namespace, and filename. With this change, all devices running Junos OS Evolved use thejunos
device family identifier. To emit device-specific modules that use thejunos-qfx
device family identifier, configure thedevice-specific
andemit-family-ns-and-module-name
statements at the[edit system services netconf yang-modules]
hierarchy level.
Routing Protocols
-
Optimized mesh group routes (QFX5110, QFX5120, QFX5130, QFX5700 and ACX Series)—
show route snooping
for inet.1/inet6.1 table andshow route snooping table inet.1/inet6.1
displays only CE mesh group routes for platforms that support EVPN-MPLS or EVPN-VxLAN multicast. In earlier releases, other mesh groups like the VE mesh group were also displayed.
System Management
-
Additional
Upgrade
fields for theshow system applications detail
command (ACX Series, PTX Series, and QFX Series)—Theshow system applications detail
command and corresponding RPC include additionalUpgrade
output fields. The fields provide information about notifications and actions related to various upgrade activities.
Software Installation and Upgrade
-
configuration
andno-configuration
options for therequest system snapshot
command (QFX Series)—When you omit or include theconfiguration
option, therequest system snapshot
command copies the /config directory and the configuration stored for each installed software version to the alternate solid-state drive (SSD) as part of the snapshot. You can use theno-configuration
option to exclude the /config directory and the configuration stored for each installed software version from the snapshot.
VPNs
-
Increase in revert-delay timer range— The
revert-delay
timer range is increased to 600 seconds from 20 seconds.[See min-rate.]
-
Configure min-rate for IPMSI traffic explicitly— In a source-based MoFRR scenario, you can set a min-rate threshold for IPMSI traffic explicitly by configuring
ipmsi-min-rate
underset routing-instances protocols mvpn hot-root-standby min-rate
. If not configured, the existingmin-rate
will be applicable to both IPMSI and SPMSI traffic.[See min-rate.]
