4 CloudBridge Virtual WAN These release notes describe the Citrix CloudBridge software release which is focused on the Virtual WAN Standard Edition and Virtual WAN Enterprise Edition. The CloudBridge Virtual WAN software aggregates the bandwidth of multiple WAN links. Each packet is routed to the most appropriate WAN link based on real-time network conditions and the application requirement. The Virtual WAN software is fault tolerant and can intelligently route traffic around degraded or failed WAN links in sub-second timeframes to preserve user productivity. For latencysensitive traffic like VoIP and XenApp, the Virtual WAN can deliver a higher end user experience by duplicating packets across WAN links to preserve session quality in the face of high packet loss or failed links. Traffic is secured through optional 256-bit AES encryption to preserve data privacy. All hardware appliances are equipped with fail-to-wire interfaces to allow pass-through of traffic in the event of hardware failure. These appliances can also be deployed in a high availability configuration for maximum uptime. With the CloudBridge software release Citrix is introducing the Enterprise Edition for the branch, combines Virtual WAN and WAN Optimization technologies together in one product. In addition, the software release supports a new high end Virtual WAN appliance, the CloudBridge 5100-VW. For more information about the CloudBridge Virtual WAN and CloudBridge Enterprise Edition, see the CloudBridge Virtual WAN Administration Guide. What's New in Release In addition to introducing the Enterprise Edition, CloudBridge Release includes many new features and substantial improvements for Virtual WAN Edition. 1. WAN Optimization. This feature is available only on CloudBridge 1000 and CloudBridge 2000 appliances with the Enterprise Edition. It provides: ICA Optimization Supports the high-quality delivery of Apps and Desktops with Citrix XenApp amd XenDesktop CIFS/SMB2/SMB3/MAPI Acceleration Accelerates file- and -based operations based on Microsoft protocols and applications including the Microsoft Office suite TCP Flow Control Page 4

5 TCP flow control and congestion management optimization to accelerate WAN traffic Fast Recovery from lossy transmission situations Application Visibility Export of AppFlow records for application insights through Citrix NetScaler Insight Center 2. New high-end CloudBridge-5100 platform supporting Virtual WAN Edition. 3. Metered Links, which enable: Usage based Alerting alerts on reaching or exceeding user defined byte count thresholds Link of Last Resort Use designated links only when other non-metered links are down or degraded Reduced Overhead Conserve bandwidth by lowering path quality assessment frequency 4. IPSec tunneling for Virtual Paths, with the following benefits: Use of well known, widely adopted encryption protocols to secure virtual path traffic Packet level confidentiality and authentication Resilient IPSec Tunneling to prevent the need for tunnel reinitiation as long as one WAN link is up 5. Path State Configurability (Virtual WAN & Enterprise Edition) ), offering new options for configuring the sensitivity of the state of a WAN link 6. LAN-side GRE tunnels to facilitate deployments of CloudBridge virtual appliances for AWS 7. Forward SSH authentication notices to a remote syslog server when syslog is enabled 8. More detailed information on why path state has transitioned from GOOD to BAD 9. User-generated SSL certificates on appliances. Users can now upload SSL certificates for the appliance s IP address (signed by the appropriate Certificate Authority) through the GUI. 10. Private MPLS WAN Link definition that allows users to define MPLS queues for a single WAN Link, eliminating the need to create a separate WAN Link, with its own Virtual IP (VIP) address, for each MPLS queue. This capability is included in both the Virtual WAN & Enterprise Edition. Limitations Enterprise Edition appliances are designed for branch-side deployment only. Enterprise Edition appliances cannot be joined to Active Directory Domains. To accelerate file or Microsoft Exchange servers in a branch, a standalone WAN Optimization deployment is required. Secure peering, needed for WAN optimization of signed SMB or encrypted MAPI traffic. This is only supported on data path IPs and will not work over the management IPs. Page 5

6 Automatic Secure peering of an Enterprise Edition appliance from a standalone WAN Optimization appliance requires that the datacenter side WAN Optimization appliance is running release 7.4.x or later. Virtual WAN Enterprise Edition does not support WAN optimization of SSL traffic. Known Issues in Issue ID : After you run and complete the 'Change Management' process for the first time, the active package is not shown. Click again on Activate Staged to complete the activation process. Issue ID : During change management for changing an IPsec profile from IPSEC AES-256/SHA-256 to AES-128/SHA1 in a multi-site (over 100) network, the UI shows the message Unable to obtain system data because the system is busy. Click Refresh on your browser to retry. Change management process is completed and functional after a few minutes. Issue ID : When XEN private networks are used for CloudBridge VW VPX along with CloudBridge WAN Optimization VPX, the Checksum.SendForceSW parameter available through support.html page on WAN Opt UI must be turned off. Issue ID : In Virtual WAN Center, events raised for WAN PATH objects are visible in the Event Viewer, but are not available for or syslog notifications. Issue ID : A Disk usage for the active OS partition is at n% message appears when multiple attempts are made to upload a single bundle (upg) package during the upgrade process is still in progress. The recommended workaround is to wait about 20 minutes for the upgrade process to complete. Licensing CloudBridge 8.x introduced a new set of licenses specific to the Virtual WAN solution. Earlier CloudBridge licenses, including those compatible with release 7.x, are not supported with the CloudBridge Virtual WAN release. The existing process to obtain CloudBridge licenses remains consistent with the CloudBridge 8.0.x release. Once obtained, the licenses can be consumed and activated through the appliance s web interface. The following table lists all the licenses that support the CloudBridge release: S.No Platform Edition License Model 1 Virtual WAN VPX V10VW V20VW V50VW V100VW 2 Virtual WAN VW VW VW Virtual WAN VW-020 Page 6

7 Enterprise 1000 Virtual WAN Enterprise Virtual WAN Virtual WAN VW VW EE EE EE VW VW EE EE EE VW VW VW VW VW VW VW-3000 VPX models allows 10, 20, 50 and 100 Mbps bandwidth licenses. At least two 2.1 Ghz CPUs are required in order to support the VPX instances. Install & Configuration Guide Please refer to the CloudBridge Virtual WAN Administration Guide for more details related to the supported appliance models, features and configuration aspects of the Citrix Virtual WAN solution. CloudBridge WAN Optimization appliance on data center side should be running with build, for secure peering functionality to work with VW-EE appliance. DHCP Server should be configured in your network for Virtual WAN Center, to acquire an IP address. NTP and Date/Time should be synced properly across VW MCN and VW Center. Upgrade procedure from CloudBridge to There are two main scenarios 1. Upgrade existing appliances with working VW Configuration 2. Upgrade new appliances with factory shipped Appliances shipped with 8.0.x image are not supported to upgrade to enterprise edition. Page 7

8 1. Upgrade appliances with working VW Configuration Pre-requisites: 1. To change existing appliance to Enterprise Edition (CB1000-EE or CB2000-EE), appliances are required to have as a base image. 2. Have a working VW configuration (Virtual paths are already established from MCN to branch sites) Upgrade Steps: 1. Branch Site: On the branch site Virtual WAN appliance, use Single bundle upgrade package (CB-VW-PKG UPG) a. Navigate to Configuration > System Maintenance -> Update Software -> Update Operating System Software b. Click on the Choose File button and provide the CB-VW-PKG UPG file c. Click on Upload and Upgrade d. Allow the appliance approximately 20 minutes to run through the upgrade procedure Do not unplug the appliance during this process. Run a continuous ping to the management IP to identify when the box has completed the upgrade process. When the management IP becomes responsive, you can refresh the browser. Note: VW VPX configured as branch site does not require Single bundle upgrade. 2. MCN: On the MCN Virtual WAN appliance, use Single bundle upgrade package (CB-VW-PKG UPG) e. Navigate to Configuration > System Maintenance -> Update Software -> Update Operating System Software f. Click on Choose File option to provide the CB-VW-PKG UPG file g. Click on Upload and Upgrade This step may take about 20 minutes to complete. Do not unplug the appliance during this process. Run a continuous ping to the management IP to identify when the box has completed the reboot. h. The UI should automatically redirect to the Change Preparation step of the Change Management process. i. Click on Overview (that is present in Change Management ) j. It would redirect the request to the VW UI, for admin login credentials k. In Change Preparation -> Click on Next l. Wait while the system is Preparing packages for transfer m. Once complete, in Appliance Staging -> Click on Stage Appliances n. In Activation -> Click on Activate Staged o. Then click Done Page 8

9 3. Verify the VW version changed to (on both MCN and branch site) and the Virtual path is established. (It might take about a minutes, for the licenses to get activated). Refresh the browser, and validate for proper licensing, if you see any anomalies. Important Notes: 1. Warning banner that mentions about Disk Usage for Active OS Partition can be ignored 2. Intermittent SSO Session might be timed out, when accessing the WAN Optimization node Workaround: Please re-login and continue. 2. Upgrade new appliances with factory shipped Choose which device needs to be MCN. Promote the device as MCN (Configuration -> Appliance Settings - > Administrator Interface -> Miscellaneous -> Switch Console). Download applicable cb-vw_<appliance-model>_ tar.gz file for the MCN device. Example: CloudBridge 1000 VW is chosen to be MCN. Download cb-vw_cb1000_ tar.gz. Upgrade this appliance using the downloaded package above (System Maintenance -> Update Software -> Re-image Virtual WAN Appliance software -> Click on Browse option to provide the cb-vw_cb1000_ tar.gz file - > Click on Upload ). Select Accept and Click on Install to proceed. 2. Create a new Virtual WAN Network Configuration file (using Configuration -> Virtual WAN -> Configuration Editor). Export the configuration to Change Management. Do not perform Change Management workflow in this step. 3. Perform single bundle update on this MCN device and all other devices. For non- MCN device if the appliance model is VPX, then skip this step. Download CB-VW-PKG upg file. Install the downloaded upg file (System Maintenance -> Update Software -> Update Operating System Software ) on both MCN and non-mcn device. On non-mcn device, the Update software UI would show the status as Software Update Preparing for install Please wait for 20 Minutes. Do not unplug the appliance during this process. Run a continuous ping to the management IP to identify whether the box has completed rebooted (ping should fail initially and after 20 minutes, it should succeed). 4. Install VW license on the MCN device. 5. Perform MCN Change management After the installation completes, perform change management workflow on the MCN. Download active packages for all the VW devices. After you run and complete the 'Change Management' process for the first time, the active package is not shown. Click again on Activate Staged to complete the activation process. 6. Install the VW/VW-EE License on all non-mcn devices 7. For each non-mcn device, upload the corresponding packages that were downloaded in step 5 and perform local change management work flow. Page 9

10 8. Enable Virtual WAN Service on MCN and non-mcn devices. Compatibility The CloudBridge Virtual WAN release requires that all appliances on the Virtual WAN network have the same software release.
