I have three switches, A and B and C as show in attached picture, switch A connected with firewall device and provide internet connection to switch B and C. Switch B is connected to switch C, while switch C connected to switch A. PC at switch B need to access to PC at switch A for their share files. Company will sell the PC at switch B to customer, so the PC ip address and mac address at switch B will change frequently.
I planning to subscribe another internet plan (internet B as show in picture) and direct plug in the new internet modem/router to switch B while switch B still connected to switch C for access to share folder and internet A. Because some user at switch B need to access to share folder and internet A.
How do I assign particular port at switch B to access internet B only, and no access to internet A? Because some user at switch B are hogging internet A bandwidth and make internet speed slow down. Is there any way to limit the speed of the particular port to lower than 30KB/s? The attached picture show the network diagram and switch route default settings.
