General Routing

  • The Routing Engine boots from the secondary disk when you:

    • Press the reset button, on the RCB front panel, while Routing Engine is booting up but before Junos is up.

    • Upgrade software, by booting from the network using the request vmhost reboot network command, and the system fails to boot from the network.

    • Upgrade BIOS and the upgrade fails.

    • Reboot and the system hangs before Junos is up.

NFX150 Series Devices

  • On NFX150 devices, the PPPoE session does not come up on the interface due to the hardware limitation for both tagged and untagged cases. As a workaround, enable the promiscuous mode on the interface. PR1347830

Known Issues

This section lists the known issues in hardware and software in Junos OS Release 18.3R3 for the NFX Series devices.

For the most complete and latest information about known Junos OS defects, use the Juniper Networks online Junos Problem Report Search application.

Known Issues: 18.3R3

  • On NFX 150 devices,connectivity fault management (CFM) is not supported on circuit cross-connect (CCC) interfaces. PR1311588

  • On NFX150 devices, FTP displays an error message, ftpd[14105]:bl_init: connect failed for `/var/run/blacklistd.sock'(No such file or directory). PR1315605

  • On NFX150 running Junos OS Release 18.2R1, AMI does not support ME region upgrade support using ESRT upgrade method. Hence, with latest BIOS ABDN_U_POR3-SFP_11.37.00, BIOS upgrade for ME region is not supported. PR1333875

  • During BIOS upgrade process, it does not display the existing BIOS version or the new BIOS version to which it is being upgraded. Similarly, it does not display the BIOS version when a lower version of BIOS is getting upgraded to a higher version of BIOS. PR1342573

  • Under some circumstances, FPC0 ukern of NFX150 may crash and restart. The FPC recovers automatically and it does not crash again after the recovery. There is no known workaround. PR1347629

  • On NFX 150 devices, dev key revocation is not supported by BIOS. Dev key revocation is to prevent customers from installing Dev signed image by mistake on their setup. PR1344738

  • On NFX150 devices, syslog messages do not display xauth client authentication information such as assigned IP address and DNS. PR1305078

  • During BIOS upgrade process, it does not display the existing BIOS version or the new BIOS version to which it is being upgraded. Similarly, it does not display the BIOS version when a lower version of BIOS is getting upgraded to a higher version of BIOS. PR1342573

  • On NFX150 devices, only the CFM cells that are configured for MEP levels are exchanged across xDSL MEP. Other MEP level CFM packets are dropped, whereas for Ethernet All MD level along with above level will be exchanged. PR1409576

  • On NFX150 devices, when NAT rules are configured with the IPv6 prefix length as 96 and the port overloading capacity as 2, there is a mismatch in the value of the single port range when IPv6 packets are sent from the VM. PR1438943

  • On NFX150 devices, the show security dynamic-address command does not work for port 3. PR1448594

Resolved Issues

This section lists the issues fixed in the Junos OS Release 18.3R3 for NFX Series devices.

For the most complete and latest information about known Junos OS defects, use the Juniper Networks online Junos Problem Report Search application.

Resolved Issues: 18.3R3

  • On NFX150 devices, SNMP does not work for the following commands:

    • show snmp mib walk jnxIpSecTunMonOutEncryptedBytes

    • show snmp mib walk jnxIpSecTunMonOutEncryptedPkts

    • show snmp mib walk jnxIpSecTunMonInDecryptedBytes

    • show snmp mib walk jnxIpSecTunMonInDecryptedPkts

    • show snmp mib walk jnxIpSecTunMonLocalGwAddr

    • show snmp mib walk jnxIpSecTunMonLocalGwAddrType

    PR1386894

  • On NFX250 devices, when you issue the request support information command, the configuration and counter data are missing for JDM. PR1413674

  • When you run the show chassis fpc or show chassis fpc details command, the Temperature field in the command output message is displayed as Testing. PR1433221

  • Version compare in phc may fail causing the phc to download the same image. PR1453535

Resolved Issues: 18.3R2

  • When ALG is enabled, some ALG traffic might fail to match the interface filter after packet reinjection. The reason is that mbuf copy command does not copy the filter information to new mbuf. As a workaround, disable the ALG. PR1339912

  • Class super-user does not have group permission to create folder under /var/third-party. This allows non-root users of super-user class to create folders and files in /var/third-party. As a workaround, manually set the permission of /var/third-party through chmod 1777 /var/third-party. PR1352561

  • On NFX250-S1E devices, the jsxe0 interface might not get IP address from the DHCP server. PR1354596

  • NFX250 devices running Junos OS Release 18.1R1 do not provide product details to super-user when queried using netconf. As a workaround, log in as a root user. PR1356896

  • The init.xml file is corrupted when there is an unexpected power outage, and the VNF fails to instantiate. When the init.xml file is corrupt or missing, the NFX device will recreate the init.xml file and instantiate the VNF by using the recreated init.xml file. As a workaround, check if the vnf instantiates after multiple power outages. PR1373997

  • NFX3/ACX5448:LIBCOS_COS_TVP_FC_INFO_NOT_FOUND: Forwarding-class information not specified message is displayed when you commit on configuration mode. As a workaround, run the command, set system syslog user * match "!(LIBCOS_COS_TVP_FC_INFO_NOT_FOUND: Forwarding-class information not specified)" and commit. PR1376665

  • The dialer-options route configuration in LTE interface does not work in user-defined routing instance. It works only in root routing instance. PR1389907

Resolved Issues: 18.3R1

There are no fixed issues in Junos OS Release 18.3R1 for the NFX Series.

Documentation Updates

There are no errata or changes in Junos OS Release 18.3R3 documentation for NFX Series.

Migration, Upgrade, and Downgrade Instructions

This section contains the procedure to upgrade Junos OS, and the upgrade and downgrade policies for Junos OS for the NFX Series. Upgrading or downgrading Junos OS might take several hours, depending on the size and configuration of the network.

Upgrade and Downgrade Support Policy for Junos OS Releases

Support for upgrades and downgrades that span more than three Junos OS releases at a time is not provided, except for releases that are designated as Extended End-of-Life (EEOL) releases. EEOL releases provide direct upgrade and downgrade paths—you can upgrade directly from one EEOL release to the next EEOL release even though EEOL releases generally occur in increments beyond three releases.

To upgrade or downgrade from a non-EEOL release to a release more than three releases before or after, first upgrade to the next EEOL release and then upgrade or downgrade from that EEOL release to your target release.

For more information on EEOL releases and to review a list of EEOL releases, see https://www.juniper.net/support/eol/junos.html.

Basic Procedure for Upgrading to Junos OS Release 18.3

When upgrading or downgrading Junos OS, use the jinstall package. For information about the contents of the jinstall package and details of the installation process, see the Installation and Upgrade Guide. Use other packages, such as the jbundle package, only when so instructed by a Juniper Networks support representative.

Note

The installation process rebuilds the file system and completely reinstalls Junos OS. Configuration information from the previous software installation is retained, but the contents of log files might be erased. Stored files on the device, such as configuration templates and shell scripts (the only exceptions are the juniper.conf and ssh files), might be removed. To preserve the stored files, copy them to another system before upgrading or downgrading the device. For more information, see the Installation and Upgrade Guide..

Note

We recommend that you upgrade all software packages out of band using the console because in-band connections are lost during the upgrade process.
