Known Issues


This section lists known issues in Juniper Networks CSO Release 5.2.0.


  • On an enterprise hub, whenthere are no non-data center departments, the SD-WAN policy deploy job may return the following message and fail:

    No update of SD-WAN policy configuration on device due to missing required information.

    Workaround: There is no functional impact; the deploy job completes successfully when a non-data center department with a LAN segment is deployed on an enterprise hub.

    Bug Tracking Number: CXU-31365

  • While provisioning a dual CPE SRX Series cluster as an enterprise hub with the multi-access shared bearer (MASB) configuration, the stage-1 configuration fails to commit because untagged logical interfaces are not supported on the device interface when MASB is configured.

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-42201

  • Traffic is not load balanced in the active/active mode with cloud breakout for IPsec tunnels.

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-43136

  • Jobs to update NAT are not getting triggered. Therefore, the NAT port assigned to a dynamic VPN (DVPN) IPsec configuration is incorrect.

    Workaround: Delete and create the DVPN tunnels manually by using the CSO GUI.

    Bug Tracking Number: CXU-46183

  • While creating an IPsec tunnel between an Internet link behind NAT in a spoke and an MPLS link in an enterprise hub, a wrong NAT interface is configured on the IPsec tunnel. Therefore, the tunnel fails to be created.

    Workaournd: You must trigger a NAT update job immediately to assign the correct NAT IP-to-static tunnel.

    Bug Tracking Number: CXU-46185

  • When configuring a DVPN tunnel between two devices, if one device is not functional while the other is functional, the job to configure the DVPN tunnel should not configure the DVPN tunnel on the device that is functional.

    Workaournd: There is no known workaround. If the DVPN configuration tunnel is configured on the functional device, delete the configuration manually.

    Bug Tracking Number: CXU-46188

  • The infotip for the ADSL_ENCAP parameter in the SRX as SDWAN CPE device profile incorrectly suggests to enter the encapsulation for connecting to the ADSL service provider through PPPoE. The ADSL_ENCAP parameter does not apply to PPPoE, but to PPPoA.

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-46189

Hybrid WAN

  • Fortinet service chaining is failing on NFX250.

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-42188


  • The phone-home process might not be triggered if you zeroize an EX Series switch and commit the configuration manually on the switch.

    Workaround: To trigger the phone-home process, run the delete chassis auto-image-upgrade command and commit the delete operation.

    Bug Tracking Number: CXU-39129

  • The deployment of a port profile fails if the values you have configured for the firewall filter are not supported on the device running Junos OS.


    • Edit the firewall filter.

    • Update the values according to the supported configuration specified for a firewall filter, in this link.

    • Redeploy the port profile.

    Bug Tracking Number: CXU-39629

  • CSO is unable to configure access ports on the EX4600 and EX4650 devices after you zeroize the device because a default VLAN is configured on all the ports after zeroizing.

    Workaround: Load the factory-default configuration if you zeorize the EX4600 and EX4650 devices or delete the default VLAN configuration from all the ports of the members by using commands such as # wildcard range delete interfaces xe-0/0/[0-23].

    Bug Tracking Number: CXU-42865

  • When adding a switch to an already provisioned site, the site state is set to Provisioned in CSO. Therefore, a link to copy the stage-1 configuration for manually activating the EX Series device does not appear. You must set the state of a site to Provisioned only when all the devices in the site are provisioned.

    Workaround: Delete the device from CSO and add the device again after rectifying the reason for provision failure.

    Bug Tracking Number: CXU-40647

  • The chassis view for an EX2300 Virtual Chassis appears blank when the device resources are used up and the request for getting a response from the device times out.

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-42866

  • ZTP of an EX Series switch fails if you add the switch behind an enterprise hub.

    Bug Tracking Number: CXU-38994

  • You cannot edit a standalone SD-LAN site although the Edit Site button is enabled.

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-45918

  • While configuring an SD-WAN site with an EX Series switch, the VLAN value that you enter for a LAN segment is not saved if you enable CPE ports in the LAN segment.

    Workaround: Reenter the VLAN value after you add the CPE ports to the LAN segment.

    Bug Tracking Number: CXU-45943

  • The chassis view of an EX Series Virtual Chassis may not reflect the correct status of the Virtual Chassis ports (VCPs).

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-44880

  • When you select all VLANs for deletion and if one or more of the selected VLANs is connected to a CPE port, the VLANs are not deleted. An error message appears and a job to delete the VLANs is created in CSO. The jobs appear to be successful and the status of the VLANs appear as Delete Pending.

    Workaround: When VLANs are selected for deletion and if any of the VLANs is connected to a CPE port, remove the VLAN configuration from the CPE port and then delete the VLANs.

    Bug Tracking Number: CXU-44966

  • CSO may not detect an EX Series switch connected behind an SRX Series device running Junos OS Release 19.3R2-S1 or Release 19.3R2-S2. This is because the port connecting the EX Series switch and the CPE is blocked by RSTP running on the SRX Series device and hence no IP address is assigned by DHCP to the port.

    Workaround: Disable RSTP on the SRX Series device or add the set protocols rstp force-version stp statement as part of the stage-2 configuration on the SRX Series device.

    Bug Tracking Number: CXU-46760

Security Management

  • If a provider hub is used by two tenants, one with public key infrastructure (PKI) authentication enabled and other with preshared key (PSK) authentication enabled, the commit configuration operation fails. This is because only one IKE gateway can point to one policy and if you define a policy with a certificate then the preshared key does not work.

    Workaround: Ensure that the tenants sharing a provider hub use the same type of authentication (either PKI or PSK) as the provider hub device.

    Bug Tracking Number: CXU-23107

  • If UTM Web-filtering categories are installed manually (by using the request system security UTM web-filtering category install command from the CLI) on an NFX150 device, the intent-based firewall policy deployment from CSO fails.

    Workaround: Uninstall the UTM Web-filtering category that you installed manually by executing the request security utm web-filtering category uninstall command on the NFX150 device and then deploy the firewall policy.

    Bug Tracking Number: CXU-23927

  • If SSL proxy is configured on a dual CPE device and if the traffic path is changed from one node to another node, the following issue occurs:

    • For cacheable applications, if there is no cache entry the first session might fail to establish.

    • For non-cacheable applications, the traffic flow is impacted.

    Workaround: None.

    Bug Tracking Number: CXU-25526

  • When CSO is upgraded to release 5.2.0, there are 15 LAN ports in the SRX1500 dual CPE device template, when the actual number of LAN ports should be four.

    Workaround: Clone the SRX1500 dual CPE device template and remove the extra 11 LAN ports from the template. Use the cloned device template to onboard an SRX1500 dual CPE device to CSO.

    Bug Tracking Number: CXU-45889

Site and Tenant Workflow

  • On a site with an NFX250 device and EX Series switch, the EX Series switch is not detected if there are no LAN segments.

    Workaround: You can view the data from the Monitoring >Application Visibility page or Monitoring >Traffic Logs page.

    Bug Tracking Number: CXU-39167

  • While adding a spoke site if you add and associate one or more departments with one or more LAN segments, sometimes the department's VRF tables might not be created at the enterprise hub. This causes the enterprise hub's 0/0 (default) route to be missing in the spoke site department's VRF tables.

    Workaround: Delete and redeploy the LAN segments.

    Bug Tracking Number: CXU-37770

  • When DVPN tunnels (GRE_IPSEC tunnels) are established between a pair of SRX3XX devices that have Internet WAN links behind NAT, the GRE OAM status of the tunnels is displayed as DOWN and hence the tunnels are marked as DOWN and not usable for traffic.

    Workaround : Disable the GRE OAM keepalive configuration to make the tunnel usable for traffic.

    Bug Tracking Number: CXU-41281

  • The health check in the CAN node fails while you run the script on the startup server during the HA deployment. This is because the Kafka process is inactive in one of the CAN nodes.


    1. Log in to the CAN node.
    2. Run the docker restart analyticsdb analytics controller command and wait for around 10 minutes.
    3. Rerun the script on the startup server.
    4. If the CAN node components are still unhealthy, repeat 2 and 3.

    If all the components are healthy, then proceed with the installation.

    Bug Tracking Number: CXU-41232

  • Alarms are not getting generated if the date and time is not in sync with the NTP server.

    Workaround: CSO and devices must be NTP-enabled. Make sure CSO and device time are in sync.
