Upgrade (OS) Process
The new WANOP OS Kernel upgrade is supported from which SD-WAN release?
Citrix SD-WAN release 10.1 and later.
Is the new OS supported on all SD-WAN platforms?
Yes. The OS upgrade is supported on all SD-WAN WANOP (VPX, Physical, Cloud), and Premium/Enterprise edition appliances.
What are the WANOP VPX profiles (RAM/Disk/vCPU) that are supported with release 10.1?
- 6GB RAM, 100GB Disk and 2 vCPUs
- 6GB RAM, 250GB Disk and 2 vCPUs
- 8GB RAM, 500GB Disk and 4 vCPUs
- 16GB RAM, 500GB Disk and 4 vCPUs
What are the key feature differences between WANOP running with release 10.0 or lower versus 10.1?
| Feature | 10.0 or earlier | 10.1 or later | Comments |
|---|---|---|---|
| Video Caching support on WANOP | supported | Not supported | none |
| Minimum RAM requirement for WANOP VPX | 4GB RAM | 6GB RAM | none |
| WANOP VPX deployment wizard | supported | Not supported | none |
| Primary / apA Adapter Management IP address for WANOP VPX | DHCP is disabled by default | DHCP is enabled by default | none |
| Upgrade support on existing standalone WANOP VPX on Citrix Hypervisor | supported | not supported. Fresh SD-WAN 10.1 XVA image should be imported | none |
| Upgrade support on Physical WANOP platform that have Citrix Hypervisor 6.0 Hypervisor version (Platforms that are shipped with 7.2.2 or earlier factory base image version would have Citrix Hypervisor 6.0 version) release 10.1 | supported | You have to upgrade Citrix Hypervisor to 6.5 version (using WANOP Citrix Hypervisor 6.5 upgrade bundle) and then perform WANOP 10.1 upgrade | Clicking on “Configuration” GUI, would display Citrix Hypervisor hypervisor version |
Upgrade of WANOP VPX running on standalone Citrix Hypervisor (with WO build 10.0 or earlier) to 10.1 version is that supported, If not, why?
This upgrade is not supported because of PV to HVM conversion. You have to provision a fresh SD-WAN release on 10.1 Citrix Hypervisor WANOP VPX using the XVA image.
Upgrade of WANOP VPX running on standalone ESXi / Hyper-V (with WO build 10.0 or earlier) to 10.1 version is that supported, If not, why?
This upgrade is supported. Before upgrade, please be aware of the new RAM resource requirement changes.
Upgrade of WANOP on physical appliance (with WANOP build 10.0 or earlier) to 10.1 version is that supported, If not, why?
This upgrade is supported. Prerequisite for this upgrade is to have the hosting Citrix Hypervisor Hypervisor (on physical SD-WAN appliance) to have Citrix Hypervisor version 6.2 / 6.5 or higher version. This can be verified by using the Configuration tab.
If the physical WANOP appliance is not running with Citrix Hypervisor 6.2 / 6.5 or higher, what does the user have to perform?
You have to upgrade Citrix Hypervisor, before upgrading SD-WAN WO version.For example, in this below use case, let us consider planning to upgrade SD-WAN 800 WANOP platform running with 7.2.2 (that has Citrix Hypervisor 6.0 version).
-
While upgrading this appliance to SD-WAN 10.1 release, the following error message would occur.
-
Upgrade Citrix Hypervisor to 6.5, using “ns-sdw-xen65-pkg_v1.5.upg” (this can be downloaded from Citrix Download website.
-
If SD-WAN WO does not have 9.0 or later version, then upgrade to Citrix Hypervisor 6.5 would not happen. The below error message would appear.
-
Let us assume, the user have upgraded the WO version to 10.0.2 now.
-
Now, upgrade Citrix Hypervisor to 6.5, using “ns-sdw-xen65-pkg_v1.5.upg”.
-
Now, upgrade SD-WAN to 10.1 release.
Client to Server ICMP Ping is working fine, but TCP traffic is not going through the WANOP VPX appliance (disabling WANOP traffic processing works fine)?
Check the firewall settings on the Client, Server and Router. When WANOP VPX or Client/Server are hosted as VM, make sure that checksum is disabled on the end hosts VM.
Example Linux Commands:
ethtool -K eth0 tx off
ethtool -K eth0 rx off
ethtool --offload eth0 tx off
ethtool --offload eth0 rx off
Enable the “Checksum.SendForceSW” parameter on both WO VPXs should be “ON”.
Example:
Checksum.SendForceSW on
Is there any change to SDWAN SE/EE/WO Appliance upgrade process due to new WO OS Kernel?
No.
