I created several vlans in a 2950 switch. I set vlan1 as with an ip address and I was able to remotely connect to the switch when I added an ip address to vlan 10 and enabled it, I suddenly lost connection to the switch. Note that I added ports 1-3 to vlan 10 and there is nothing plugged into these ports now. Any ideas as to why I lost connection when I added that ip address.
I have this problem too.
