Can't ping my subnet under another switch

[Piotr_Jakubczyk]

Hello i have two switch one x440 other x460 and cant ping hosts under another switch with diffret subnet. How to configure switches to make communication possible? Or do i need to make static routing?

Hi Piotr, I'm guessing the mask in your diagram is /24 (255.255.255.0) instead of /16 (255.255.0.0).

If that's true, then:

PC1 to PC2 works even in different subnets because both PCs are on the same switch and the switch uses just 1 MAC address for all interfaces (except mgmt port)
PC1 to PC4 works because they are on the same subnet (192.168.1.x)
PC1 to PC3 does not work because you they are on different subnets and different switches

You just need to do "enable ipforwarding" on both switches.

From your diagram it looks like your PC's are using a /16 mask and the switch IP's are using a /24 mask. I would fix that first. and if you plan to do routing make sure to "enable ipforwarding"
