What’s Changed

Flow-label configuration status for EVPN ELAN services—The output for the show evpn instance extensive command now displays the flow-label and flow-label-static operational status for a device and not for the routing instances. A device with flow-label enabled supports flow-aware transport (FAT) flow labels and advertises its support to its neighbors. A device with flow-label-static enabled supports FAT flow labels but does not advertise its capabilities.

Prior to this change when route sharding is configured the output of CLI "show route" commands included information about sharding. After the change the use must add the "rib-sharding all" argument to CLI "show route" commands to display sharding information.

Instance type change is not permitted from default to L3VRF in open configuration (ACX Series, EX Series, MX Series, QFX Series, SRX Series, vMX, and vSRX)–DEFAULT_INSTANCE is the primary instance that runs when there is no specific instance type configured in the route <codeph>set routing-options?<codeph>. Any instance you explicitly configure is translated into set routing-instance r1 routing-options?. The issue appears in translation, when you change instance type DEFAULT_INSTANCE (any instance to DEFAULT_INSTANCE) to L3VRF or L3VRF to DEFAULT_INSTANCE. As a result, such changes are not permitted. Additionally, DEFAULT_INSTANCE can only be named DEFAULT, and DEFAULT is reserved for DEFAULT_INSTANCE, therefore allowing no such changes.

Display flexible algorithm information for SRv6 locators in TED database-Use the show ted database extensive command to view the metric, flags, and flexible algorithm information associated with a SRv6 locator. Prior to this release, this information was not included in the TED database.

Enhancement to the jnxRmonAlarmState (ACX Series, EX Series, MX Series, NFX Series, PTX Series, QFX Series, SRX Series)—You can now view the following additional values for the jnxRmonAlarmState when you use the show snmp mib walk jnxRmonAlarmTable: fallingThreshold (6) - If the value is less than or equal to falling-threshold risingThreshold (5) - If the value is greater than or equal to rising-threshold getFailure (7)- If the value is any value other than noError for the current internal 'get' request In earlier releases, you could view only the following status for the jnxRmonAlarmState: unknown (1), underCreation (2), or active (3).

Junos YANG modules for RPCs include the junos:command extension statement (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The Junos YANG modules that define RPCs for operational mode commands include the junos:command extension statement in schemas emitted with extensions. The statement defines the CLI command for the corresponding RPC. The Juniper yang GitHub repository stores the RPC schemas with extensions in the rpc-with-extensions directory for the given release and device family. Additionally, when you configure the emit-extensions statement at the [edit system services netconf yang-modules] hierarchy level and generate the YANG schemas on the local device, the YANG modules for RPCs include the junos:command extension statement.

Enhanced bandwidth and burst policer value (MX Series and EX9200 Series)--We've updated the default bandwidth value from 20000 to 100 pps and burst policer value from 20000 to 100 packets. This enhancement avoids the CPU usage of eventd and snmpd reaching more than 100 percent. Earlier to this release, when the system receives a violated traffic for SNMP along with other protocols traffic, the CPU usage of eventd and snmpd was reaching more than 100 percent with an error.

Starting Junos Evolved release 22.3R1, support is provided to limit Network Time Protocol (NTP) configuration to one address family (inet vs inet6). You can configure one source-address per inet and inet6 family for each routing-instance in NTP. For example, the following configuration is valid: set system ntp source-address 2620:149:1d06:100::1set system ntp source-address 10.10.10.100

Changes to the JSON encoding of configuration data for YANG leaf nodes of type identityref (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—If a YANG leaf node is type identityref, Junos devices emit the namespace-qualified form of the identity in the JSON encoding of that node. In addition, Junos devices accept both the simple (no namespace) and the namespace-qualified form of an identity in JSON configuration data. In earlier releases, Junos devices only emit and accept the simple form of an identity. Emitting and accepting the namespace-qualified identity ensures that the device can properly resolve the value in the event that the YANG data model defines an identity and a leaf node containing the identifyref value in different modules.

The file copy command supports only text-formatted output in the CLI (ACX Series, EX Series, MX Series, PTX Series, QFX Series, SRX Series, vMX, and vSRX)—The file copy command does not emit output when the operation is successful and supports only text-formatted output when an error occurs. The file copy command does not support using the | display xml filter or the | display json filter to display command output in XML or JSON format in any release. We've removed these options from the CLI.
