Known Issues


This section lists known issues in Juniper Networks CSO Release 5.3.0.


  • 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

  • Sometimes, jobs to update NAT information are not getting triggered. Therefore, NAT port assigned to a 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 that is behind NAT in a spoke to an MPLS link in an ENT hub, wrong NAT interface is configured on the IPSEC tunnel. Therefore, the tunnel fails to be created.

    Workaround: 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 DVPN tunnel should not be configured on the device that is functional.

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

    Bug Tracking Number: CXU-46188

  • VNFs are not coming up in NFX150 running on Junos OS Release 19.3R2-S3 due to non-availability of required number of CPUs.

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-49268

  • When you edit an enterprise hub site by adding a WAN link, static tunnels are not established with connected spoke sites automatically.

    Workaround: Reconfigure the static tunnels with connected spoke sites manually.

    Bug Tracking Number: CXU-44427


  • 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

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

    Workaround: For onboarding an EX Series switch behind an enterprise hub, manually configure the stage-1 configuration on the switch.

    Bug Tracking Number: CXU-38994

  • While configuring an SD-WAN site with an EX 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 (VCP).

    Workaround: There is no known workaround.

  • When you select all VLANs for deletion and if any of the selected VLAN 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 appears successful and the status of the VLANs appear as Delete Pending.

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

  • When you reboot an EX Series switch that is configured behind a CPE, the EX Series switch is unable to connect back to CSO as it does not get the DHCP information from the CPE.

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-47062

Security Management

  • 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.
