Fixed Issues

Change Management process

Issue ID 706577: During the change management staging process on an SD-WAN 1000 appliance, a branch node might remain in the unpacking phase for a long duration.

Issue ID 702890: When you use the Single-Step Upgrade feature on the change management screen, it is possible for a branch node status to show as ’Failed’ even though the change management process is successful.

Configuration

Issue ID 705855: After configuration activation, the SD-WAN service might crash when traffic flow is moved from one WAN service to another WAN service where NAT’ing is enabled.

Traffic

Issue ID 707003: In NetScaler SD-WAN release version 9.3.3, generation of STS in peak traffic or load can lead to memory issues causing the STS generation process incomplete.

Known Issues

Platform

SD-WAN VPX Appliances

Issue ID 694837: For High Availability in AWS (AWS) environment, Virtual WAN service is disabled on a NetScaler SD-WAN VPX Primary (active) appliance citing duplicate IP address when the high availability interface on the primary appliance goes down.

Issue ID 702889: RCN branch that is changed from GEO to Client does not get updated to latest build even though it has an active Virtual path available by using the RCN.

Issue ID 701517: Over provisioning of the XenServer can lead to SD-WAN VPX appliance crash.

SD-WAN 4000 WANOP and 4000 SE

Issue ID 681550: On a NetScaler SD-WAN 4000 WANOP appliance, uploading DER encoded certificate for the SSL profile is ignored and no error message is displayed in the web GUI. Only PEM encoded certificates are accepted.

SD-WAN 2100 EE

Issue ID 704923: The Domain Join/ Delegate user Pre-check Tools Summary Status table is not displayed you try to access them.

    Workaround: You can obtain the status summary by selecting the ‘More’ option in the summary dialog page.

Two Box Mode

Issue ID 681680: After a factory reset on the SD-WAN SE appliance in a two box mode, configuration sync between SD-WAN WANOP and SD-WAN SE appliances fails due to stale SSL certificates.

    Workaround: Disable and re-enable two-box mode on the SD-WAN WANOP appliance.

SD-WAN 1000 / 2000

Issue ID 681663: When you upgrade SD-WAN 1000 / 2000 appliance from release build version 9.1.2.26 to 9.2.x, a warning is displayed in the browser.

    Workaround: Perform the upgrade in an incognito mode window of the Google Chrome browser.

HDX CGP over SSL

Issue ID 690794: HDX ICA/CGP over SSL session’s behavior In Virtual WAN Standard Edition:

  • HDX sessions are not being negotiated as multi stream sessions even though MSI is enabled on the appliance and MSI+MP policies are set on incoming ICA traffic.
  • HDX traffic is classified as belonging to HTTP Secure (https) application and web family.
  • HDX traffic falls under interactive_very_low class. This can cause issues in QoS, bandwidth allocation, and so on, as application Quality of Service will not be triggered because the traffic is not classified as HDX sessions.

Configuration

Virtual WAN Configuration

Issue ID 704926: Configuration error occurs when you attempt to override service in a Virtual Path by changing the IP Rule properties.

Issue ID 704160: The Site Name in Virtual WAN configuration should be configured with alpha numeric characters between 3-15 characters only. This is due to the hostname restrictions in WAN Optimization which is required for domain join operation.

Application Steering

Issue ID 699285: The Application family added as one of the match types in the Application Object which is used for Application Routes configuration is not considered for steering.

Custom Application Reporting

Issue ID 703794: If an existing application name is changed and change management is performed, the new application name might not be listed in the SD-WAN Center under the Top Sites-> Application drop-down menu. When the page is hard refreshed, then the new application name gets listed and reported, when traffic matches the application. 

WAN GRE Tunnel

Issue ID 681171: A NetScaler SD-WAN appliance does not reassemble fragmented GRE tunnel packets properly.

Transparent proxy support for TLS 1.2

Issue ID 691900: In NetScaler SD-WAN WANOP 9.3.0, for SSL compression the SSL profile has to be configured in split mode only as transparent proxy mode is not supported.

Change Management (Single Step Upgrade) SD-WAN GUI

Issue ID 691953: During software upgrade on an appliance using a Standard Edition license, a WAN optimization related warning message appears. After the scheduled upgrade and after the WAN optimization, SVM and XenServer hotfixes are installed the warning message is cleared.

    Workaround: Clear the warning messages manually or open the SD-WAN web UI in an incognito browser window.

Issue ID 705037: In the new Global Multi-Region Summary table, the “Total Sites” value appeared is less than the sum of the remaining columns. For example; if a branch node is not connected, it is possible that the branch is counted twice; once as “Not Connected” and once as “Preparing/Staging.”

Secure Peering Certificate and Keys

Issue ID 695363: In the SD-WAN GUI, on the Secure Peering Certificate and Keys page, the CA certificate contents are displayed if the private CA radio button is selected after setting the Keystore password on a new appliance. 

    Workaround: You need to switch between the radio buttons of the ‘Private CA’ and ‘CA Certificate’ once to get the correct contents displayed under ‘Private CA’ and ‘CA Certificate’ for Secure Peering Certificate and Keys.

Multicast Traffic

Issue ID 694894: When you configure Application Quality of Service rule with match type as “Application” to match ‘icmp’ and change the class to Real-time, and mode to load balance which overrides the default rule, the multicast traffic is not processed.

Routing

Issue ID 704561:  Unable to make the routing domain as default for a site after disabling it.

Workaround:

     1. Disable site routing domain (all).      2. Enable routing domain for the site without making it default. Select Apply.      3. Make the enabled routing domain for the site as default. Select Apply.

Issue ID 705255: Dynamic routes can be installed by using path eligibility, LOCAL service as part of Import filters. In NetScaler SD-WAN 10.0, if the path becomes inactive, then all routes are termed as REACHABLE – YES, and ELIGIBLE - NO instead of REACHABLE - NO and ELIGIBLE – NO. These routes which are ineligible will stay in the remote SD-WAN routing table instead of being purged.

DPI Functionality

DPI- ICMP Functionality

Issue ID 677356: A firewall policy for blocking ICMP as an application blocks only pings (echo requests). All other ICMP types are allowed to pass through.

    Workaround: Instead of blocking ICMP as an application, block IP-protocol > ICMP.

DPI –Traffic for Top App Family as “Standard” and Top App as “Unknown Virtual protocol” for a Standard Edition appliance

Issue IDs 678373, 678339, 678545, 675063, 676017: On a NetScaler SD-WAN Standard Edition appliance, enable EDT policy for MSI+MP for Win7 and Win2K12 XenDesktop 7.12 VDAs on ports 2598, 2599, 2600, 2601 and then disable Session Reliability policy for Win7 VDA.

Workaround: Start sending internet traffic and check the monitoring flows in the Standard-Edition web management interface for Classes, Rule groups – ICAUDP and ICACGPUDP, and Firewall. Check the Dashboard and Reporting page in SD-WAN Center web management interface. The results display Top Application Family as Standard and Top Applications as Unknown Virtual Protocol.

SD-WAN Center

Issue ID 693436: The clear connections/flows clear SD WAN connection table entries and all the later ICA sessions. The SD-WAN Center dashboard shows incorrect results for HDX TCP and EDT classification sessions and reports it as “Not Classified.”

Issue ID 693026: For HDX configuration, only UDP ICA sessions are classified by ICA classifier. The Framehawk ICA session is ignored. The SD-WAN DPI fails to classify the Framehawk sessions.
