I have created 2 VLANs on a 3560 switch. Vlan1 (Native) and Vlan172. The switch is connected on a trunk port to a 2801 , which does the intervlan routing.
I can telnet to the switch on both vlans 1 and 172. However as soon as I issue an no ip address to vlan 1, i can no longer telnet to the switch on vlan172.
Why is that so?
