I am facing a problem we have 2 switches, they are connected by SFP module. we can ping from one end to another end through PC.But my client have a software (type of Monitoring) on a PC its connected on SW1 and the SW2 have some machines like Generator , Boiler etc.
Monitoring Pc can't access the traffic of these machines. But when we connected these pc and machines through TP-link switch/Hub, it worked. Any solution?
thanks Philip, its SF300 managed swithes and no have configuration there, brand new, just change the default IP.
But i think i have to mention, The PC have 100Mfull duplex and the other machines connected with switch 10Mhalf dublex. but i try to make half duplex of PC as well but no work.
these heavy machines are like big Generator, boiler etc. the monitoring machine is just PC running one software for monitoring these heavy machinery.
