My LAN consists of 2 GS1200-8 and 2 GS1200-5. At the beginning, all works fine. Now, I get an loop indication on one of them. It seem, that one switch takes over the mac from another switch. Now there are two switches with the same hardware mac. Reset on Factory Settings did not help. I also installed the firmware again, no change. Does anybody knows, how to change to individual addresses? Uwe #Home_Switch_Aug

GS1200-5 changed hardware mac-address in the LAN by itself
