Thank you for your reply.
The boards and the web server PC are set in the same IP domain, and the IP of web server PC is 192.168.2.100, the IP of board is 192.168.2.10. But they can not work properly.
I try to setup PC IP 192.168.2.100, and setup swp1 IP 192.168.2.1. Then connection PC and swp1, that web-server can find the ls1028, show as the blow picture.
But I also can not config TSN，in user guide, Click the device displayed on the homepage, and an interface description table will appear. Click the interface to jump to the configuration page. In fact, when I click the device displayed on the homepage, an inteface description table appeared, that is coccrect. But when I click the interface, the configuration page didn't appeared.
I want to know that do I must setup PC and interface of LS1028A in same network segment? And why configuraion page didn't appeared.
And I think tha there's a problem here that's similar to mine, TSN Web UI for ls1028ardb
