jusalgt2 0 Posted January 15, 2018 Good day everyone! I just need a help regarding dahua manage layer 2 switch model PFS4220-16P-250. 30 cameras 4MP with optimum/ default settings then the result was lagging. switch location are in different building, distances each switch is around 70-80 meters. I'm a bit newbie on networking and confuse on how to properly connect these switches in trunk mode to distribute bandwidth. 3 switches are plugged in in link/act gigabit ports. port number 17 or 19. anyone can help me would be appreciated. Thank you! Share this post Link to post Share on other sites
Anders 0 Posted January 16, 2018 From what I can understand from the topology you've marked ports 17 and 18 as uplinks.. But from the management chart you've set port 19 to trunk. So either you reconnect the cable from port 18 to 19 or just set port 18 to trunk. Share this post Link to post Share on other sites
