Hello, everyone!
Today, I will continue to explain the VAN. In this article, I will write about the VAN principle.
The resource profiles are used to configure logical resources. We can configure a separate set of VS parameters, thanks to the fact that VLAN and MAC addresses are independently numbered and the same flag can be set (figure 1). VxLAN (Virtual extensible Local Area Network) is used so that VSs can share an upstream port.

To ensure the isolation, security, and reliability of business customer services, physical resources such as ports are allocated to VSs. OLT ports can be assigned to board mode and port mode.

OLT ports are allocated service VSs to management VS. Ports can belong to multiple VSs if they are in shared mode. ONTs are configured specifically for service VSs, in service VS.

Virtual management ports are created. Each VS has a separate virtual IP address for management. This ensures independent access to the VS and independent management and operation. Service VS is independently configured and configuration files are saved independently. In this way, service reliability is increased. Storage of logs and alarms is also independent. This makes maintenance easier.
There are different permissions for managing VS and service VS, it depends on the modes.
Service VS can only manage the board or ports assigned to it. If the board and ports are assigned to different service VS, then they can only be managed through the managing VS.
This is the end of this article. I will continue to write about this topic in the next article >> VAN (3): Application scenario and configuring VAN.
Thank you!
