The SD-WAN Standard Edition 1000, 2000, and 2100 appliances combine virtualized instances of the SD-WAN appliance.
The SD-WAN Standard Edition 1000, 2000, and 2100 appliances are based on the Citrix branch architecture, which supports multiple virtual machines. All branch appliances contain a SD-WAN Standard Edition instance and management service instance.
The SD-WAN instance is typically used in inline mode, with the SD-WAN instance interposed between the WAN router and the LAN. The SD-WAN instance can also be deployed in virtual inline mode.
The appliance has two modes; two-port mode and four-port mode, which determine how ports 1/3 and 1/4 are used.
