Dabbling with Vlans - ports Vs. subnet
hello folks,
My question is about .. obviously.. vlans.
I have a 3Com 3300 Switch with Vlan support. I added the first 6 ports to one vlan [ID:190], the other 6 to another vlan[ID:191]. Didn't attach a Layer 3 device and just wanted to check if the switch segregates machines on different vlans. I attached a machine to port 1 and another to port 7. However, both of these are within the same subnet range - 192.168.100.0/22 [MachineA:192.168.100.10; MachineB: 192.168.100.15]
Both machines can ping each other inspite of being connected to ports which are in different vlans.
Q SHouldn't the switch prevent any communication between machines on different vlans, even if both are in the same subnet?
The switch is after all a Layer 2 device. It wouldn't be even able to process IP addresses. All it would know is which mac is in which Vlan's address table. Rite?
Thanks for reading this far..
