Deploy a Citrix SD-WAN VPX instance on a NetScaler SDX appliance
Citrix SD-WAN technology applies software-defined networking (SDN) concepts to WAN connections. The technology abstracts traffic management and monitoring from network hardware and applies them to individual applications. The result is improved performance, high-quality user experiences over geographically dispersed locations, and simplified deployment of wide-area and cloud-access networks. For more information, seeCitrix SD-WAN.
From release 12.1 49.xx, you can deploy a Citrix SD-WAN VPX instance on NetScaler SDX 14XXX and SDX 115XX appliances. For more information, see the following documents:
NetScaler SDX 14020, SDX 14030, SDX 14040, SDX 14060, SDX 14080, and SDX 14100
NetScaler SDX 11515, SDX 11520, SDX 11530, SDX 11540, and SDX 11542
Note:Only the SD-WAN VPX Standard edition is supported. For more information, seeSD-WAN VPX editions.
Deploying a Citrix SD-WAN VPX instance on an SDX appliance includes the following tasks:
- Installing the hardware: ensure the SDX hardware is properly installed. For more information, seeInstalling the Hardware.
- Setting up and configuring the SDX Management Service. For more information, seeGetting Started with the Management Service User InterfaceandConfiguring the Management Service.
- Provisioning the SD-WAN VPX instance on the SDX appliance. For more information, seeProvision the Citrix SD-WAN VPX instance on a NetScaler SDX.
- Configuring the SD-WAN VPX instance. For more information, see theConfigurationdocumentations andConfiguring the virtual path service between the MCN and client sites.
Prerequisites
Ensure you’ve the following licenses:
- Citrix SD-WAN VPX license
- NetScaler SDX platform license
Citrix SD-WAN VPX requirements
The Citrix SD-WAN VPX on the SDX platform can act both as a site and MCN. The MCN can handle 1 Gb/s bidirectional throughput and 64 sites.
Supported throughput for MCN and site
- 250 Mb/s to 1 Gb/s bidirectional throughput
- MCN supports 64 sites
Hardware requirement for supported throughput
Site
- 4 CPUs to 16 CPUs
- 4 GB to 16 GB RAM
- 60 GB to 250 GB disk storage
- Minimum 4 NICs: one for management and remaining minimum 3 for data path
Master control node (MCN)
- 4, 8, and 16 CPUs
- 16 GB RAM
- 250 GB disk storage
- Minimum 4 NICs: one for management and remaining 3 for data path, with dedicated NICs for data path
Data center topology
You can deploy a Citrix SD-WAN VPX appliance on a NetScaler SDX in policy-based route (PBR) mode or in inline mode. See scenario 1 and 2 for data center topology for these two supported modes. For more information, seeDeploying SD-WAN in virtual inline mode).
Scenario 1: Inline Mode
Scenario 2: PBR mode or virtual inline mode
Provision the Citrix SD-WAN VPX instance on a NetScaler SDX
Before you provision the Citrix SD-WAN VPX appliance, download the SD-WAN VPX image from the Citrix product download site:https://www.citrix.com/downloads/netscaler-sd-wan/.
Follow these steps to provision the Citrix SD-WAN VPX appliance.
- Log on to the NetScaler SDX appliance.
- Navigate toConfiguration > SD-WAN > Instances.
SelectSoftware Images > Uploadand upload the SD-WAN XVA file.
SelectInstances > Add. TheProvision SD-WAN Instancepage appears.
In theProvision SD-WAN Instancepage, enter the following:
a. Name
b. IP address
c. Netmask
d. Gateway address
e. Upload the XVA file
f. UnderResource Allocation, allocate resources.
g. UnderNetwork Settings, provision management interfaces and selectOKto create to provision the SD-WAN VPX instance on the SDX appliance.
Note:The SDX Management Service binds interfaces to the VPX instance in the ascending sequence of interface names. For example, if you add 1/4, and 1/1, Management Service arranges them as 1/1, 1/4. When you add new interfaces, the existing sequence is retained and a new sequence is created. For example, you add interfaces 1/2, 10/1, 1/3.The new sequence would be 1/1, 1/4; 1/2, 1/3, 10/1.
6. The SD-WAN VPX instance appears under theInstance page. Here’s an example.
To edit the instance, navigate toConfiguration > SD-WAN > Instances. Select and click the instance. Once you’ve completed editing, clickOKto save the changes.
Configuring the Citrix SD-WAN VPX instance
After you’ve created an SD-WAN instance on the SDX appliance, configure the SD-WAN instance by completing these two tasks:
Apply configuration for both MCN and site appliances.
Configure virtual path and transmit traffic.
