What's Changed

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

General Routing

  • Changes to default behavior under forwarding-table— ecmp-fast-reroute and indirect-next-hop-change-acknowledgements are enabled by default under the edit routing-options forwarding-table hierarchy. You can verify these defaults by running the show configuration routing-options forwarding-table in operational mode.

    [See ecmp-fast-reroute and indirect-next-hop-change-acknowledgements.]

  • Support added for source and destination port optimization for port ranges for IPv6 input firewall filters.

  • The show subscribers extensive client-type dhcp | display xml validate command has now been updated to display correct output instead of Duplicate data element error.

  • SFP Optics LOS alarms— SFP Optics don't support Tx laser disabled alarm, Tx loss of signal functionality alarm, and Rx loss of signal alarm as diagnostics output.

    See show interfaces diagnostics optics.

  • Change in CLI output—The CLI output for show system license bandwidth, show system license bandwidth fpc, and show system license fpc commands is updated.

    See Monitor Junos Licenses.]

  • Deprecated license trace (Junos OS Evolved)—We've deprecated the CLI option show system license liblicense-trace.

Class of Service (CoS)

  • In Junos OS Evolved, do not associate a default forwarding class name with a different queue number. Use a custom forwarding class name instead. Defining customer forwarding classes with factory default forwarding class names causes errors.

EVPN

  • Easy EVPN LAG (EZ-LAG) feature lightweight loop detection configuration change— We have updated the configuration generated by the easy EZ-LAG features commit script to use logical interface names for the lightweight leaf to server loop detection feature. The EZ-LAG commit script previously generated the loop detection configuration with physical interface names, but the loop detection feature works only for logical interfaces. The lightweight loop detection configuration uses the loop-detect statement at the edit protocols hierarchy level.

    [See Easy EVPN LAG (EZ-LAG) Configuration.]

  • Duplicate MAC detection timeout—The default setting for auto-recovery-time is 5 minutes on these platforms only.

    [See duplicate-mac-detection.]

Junos XML API and Scripting

  • Refreshing scripts from an HTTPS server requires a certificate (ACX Series, PTX Series, and QFX Series)—When you refresh a local commit, event, op, SNMP, or Juniper Extension Toolkit (JET) script from an HTTPS server, you must specify the certificate (Root CA or self-signed) that the device uses to validate the server's certificate, thus ensuring that the server is authentic. In earlier releases, when you refresh scripts from an HTTPS server, the device does not perform certificate validation. Before you refresh a script using the set refresh or set refresh-from configuration mode command, first configure the cert-file statement under the hierarchy level where you configure the script. The certificate must be in Privacy-Enhanced Mail (PEM) format.

    [See cert-file.]

Routing Protocols

  • Extension of traceoptions support for VLANs in IGMP/MLD snooping— The traceoptions option is supported under the edit routing-instance protocols igmp-snooping vlan and edit routing-instance protocols mld-snooping vlan hierarchy. traceoptions can be enabled for both specific and all vlans.

    See vlan (IGMP Snooping) and vlan (MLD Snooping).]

System Management

  • Core files generated for related processes are bundled into a compressed TAR file (ACX Series, PTX Series, and QFX Series)—When a process generates a core file and the system generates a live core for its related process, the system bundles the core files into a compressed TAR file. In earlier releases, the system does not bundle the files.

    The process pairs that support this feature are: bfdd and bfddagent; cfmd and cfmd-agent; dot1xd and dot1xd-agent; l2ald and l2ald-agent; l2cpd and l2cpd-agent; mcsnoopd and mcsnoopd-agent; ppmd and ppmdagent; routing and rpdagent.

User Interface and Configuration

  • Access privileges for request support information command (ACX Series, PTX Series, and QFX Series)— The request support information command is designed to generate system information for troubleshooting and debugging purposes. Users with the specific access privileges maintenance, view, and view-configuration can execute request support information command.

  • Changes to the show system storage command output (ACX Series, PTX Series, and QFX Series)—We've updated the show system storage command output to include only true (physical) storage and exclude any host/hypervisor level storage. In earlier releases, the output also includes a container/jail storage, which does not have a separate storage of its own.

    [See show system storage.]

  • Option to view combined disk space usage statistics for all configuration databases (ACX Series, PTX Series, and QFX Series)—The show system configuration database usage command provides the merge option. When you include the merge option, the command output displays combined disk space usage statistics for all configuration databases, including the static configuration database and all ephemeral configuration database instances.

    [See show system configuration database usage.]

  • Changes to show system statistics command output (ACX Series, PTX Series, and QFX Series)—We've updated the output fields for the following commands:

    • show system statistics mpls—We've added a new field: Packets with IPv6 explicit NULL tag.

    • show system statistics jtd—We've renamed two fields to better reflect the underlying data representation. The MPLS IPv4 packet received field is renamed to MPLS IPv4 explicit NULL packets received, and the MPLS IPv6 packets received field is renamed to MPLS IPv6 explicit NULL packets received.
