Hi ALL, im new to Cisco switches. I have been given the task of replacing the existing switches with the Cisco 300,s. I am using them on a cctv system which is transmitting the videos using codecs and wireless ptp bridges. The problem i have is that at certain KEY locations there is currently two or three seperate switches sending the Video(DATA) in two different directions/Locations. Will the switches need to be programmed so the data does not clash. If so which is the best method and how do i go about it. With the existing unmanaged switches i have a data loop occurred when all radios were connected at one end because the data was being sent and received by the same switch.
