    Bug Tracking Number: CXU-42327


  • Traffic from a spoke site that has a dynamic SLA policy enabled and is connected to an MX Series provider hub device takes asymmetric paths—that is different paths for upstream and downstream.

    Workaround: There is no known workaround.

    Bug Tracking Number: CXU-32506

  • On an enterprise hub, when there are no non-data center departments, 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

  • If the Internet breakout WAN link of the provider hub is not used for provisioning the overlay tunnel by at least one spoke site in a tenant, then traffic from sites to the Internet is dropped.

    Workaround: Ensure that you configure a firewall policy to allow traffic from security zone trust-tenant-name to zone untrust-wan-link, where tenant-name is the name of the tenant and wan-link is the name of the Internet breakout WAN link.

  • Bug Tracking Number: CXU-21291

  • While provisioning a Dual CPE SRX cluster as an enterprise hub with the multi-access shared bearer (MASB) configuration, the Stage1 configuration is failing 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


  • At times, recall with the recovery configuration fails to revert EX2300 and EX3400 devices to the recovery configuration because some devices do not have the /var/db/scripts/events directory.

    Bug Tracking Number: CXU-43550

  • The Chassis View of an EX Virtual Chassis displays the port admin status as up, and VCP link status as down for a member which is powered down.

    Workaround: There is no known workaround. You can identify that a device is down by viewing the last polled data.

    Bug Tracking Number: CXU-43552

CSO High Availability

  • In an HA setup, some of the VRRs are incorrectly reported as down even though those VRRs are up and running. This problem occurs because some of the alarms that are created when VRRs are down after a power failure fail to be cleared even after the VRRs come back online.

    Workaround: Though this issue does not have any functional impact, we recommend that you restart the VRR to clear the alarms.

    Bug Tracking Number: CXU-31448

  • In an HA setup, deployment of NAT and firewall policies fail if secmgt-sm pods fail to initialize after a snapshot process and remain in 0/1 Running state.

    Workaround: Run the following curl command from the microservices VM and make sure scemgt-sm pods comes to 1/1 Running state:

    curl -XPOST "https://<central-vip>/api/juniper/sd/csp-web/database-initialize" -H 'Content-Type: application/json' -H 'Accept: application/json' -H "X-Auth-Token: token

    Bug Tracking Number: CXU-31446

  • On an HA installation, during infrastructure deployment, sometimes services inside the Contrail Analytics Node remains in the initializing state. Because of this, the Contrail Analytics Node cannot be configured and the infrastructure deployment fails.

    Workaround: Contact Juniper support team for recovery procedure.

    Bug Tracking Number: CXU-43001

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: Onboard the site with at least one LAN segment.

    Bug Tracking Number: CXU-38960

  • On an on-premise installation, when deploying a port profile configuration fails on an EX4650 switch, CSO displays the management status of the site with EX4650 switch as provisioned even though the zero-touch provisioning (ZTP) job fails on the switch.

    Workaround: Ensure that no port profile is deployed on an EX4650 switch during ZTP.

    Bug Tracking Number: CXU-42181

  • Zero-touch provisioning 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

  • When you perform ZTP on more than one enterprise hub at the same time, ZTP for one or the other enterprise hub may fail.

    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.
