What's Changed

date_range 28-Mar-25

Learn about what changed in this release for ACX Series routers.

EVPN

  • 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.

General Routing

  • OpenConfig container names for Point-to-Multipoint per interface ingress and egress sensors are modified for consistency from "signalling" to "signaling".

  • In order to monitor vmhost storage usage: ? A new minor alarm, VMHost RE 0 Disk 1 inode usage breached threshold is introduced ? The existing minor alarm, VMHost RE 0 Disk 1 Usage is above threshold is changed to VMHost RE 0 Disk 1 Size usage breached threshold.

  • Qualification check for "ordered-by-user" — Review to check and confirm if hierarchies qualify for "ordered-by-user" list type. Once show policy-options prefix-list is initiated by the user, the hierarchies appear in the order updated by the user. This enhancement organizes the hierarchies in ascending order.

  • Data diagnostic sampling interval (ACX7100-32C and ACX7100-48L)-Data diagnostic sampling is essential for performance monitoring and should occur every 1 second. However, on the ACX7100-32C and ACX7100-48L platforms, the sampling interval is 4 seconds instead of 1 second.

  • 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.

  • Support for configuring multi-chassis protection at the global level (ACX7509)–We've enabled the multi-chassis-protection statement at the edit multi-chassis global hierarchy level for ACX7509 devices. In earlier releases, multi-chassis-protection could only be enabled at the interface level.

  • 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.

MPLS

  • 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.

    [See show ted database.]

  • Change in display of affinity constraints to hexadecimal values (MX10004, ACX7100-32C, ACX7100-48L, ACX7509, ACX7024, PTX10001-36MR, PTX10004, PTX10008, and PTX10016)-Starting in Junos OS release 22.4R1 and Junos Evolved Release 22.4R1, in the output of the show ted spring-te-policy extensive operational command, the affinity constraints will be displayed in hexadecimal format instead of decimal.

    [See show ted spring-te-policy extensive.]

Network Management and Monitoring

  • 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.

Platform and Infrastructure

  • 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

User Interface and Configuration

  • 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.
