Hi John,
How do I specify on what vlan interface should the switch ip be? I assumed
that it was vlan1 by default. But looks like I understand the problem now.
The switch by default is in vlan1 and I have specified vlan10 as 10.1.1.1
which is the default-gateway for the switch. Obviously, this is not going to
work. Looks like I have to define a new subif (f0/0.1), encap isl 1, ip addr
10.1.1.1, shut, no shut and then make the pc(10.1.1.10)part of vlan 10. I
think this would do it, right?
Please advise.
Thank you.
Kind regards,
