Hi folks,

I'm trying to configure a catalyst 3650 and need some help. I've got
two vlans that I don't want to propagate or broadcast to other
switches, so I need to configure layer 2 vlans. Can someone send me an
example of how to do this?

Thanks,
Chris

Just don't configure a layer-3 interface, or leave the layer-3
interface shutdown..

vlan 10,20
int FastEthernet 0/1
switchport access vlan 10
int FastEthernet 0/2
switchport access vlan 10
int FastEthernet 0/3
switchport access vlan 20
int FastEthernet 0/4
switchport access vlan 20
no int Vlan 10
no int Vlan 20

If you have multiple switches in a network and need certain vlans
contained to a group of switches, don't use VTP.

VTP would be configured in Transparent mode, and the switches local vlan
database would only contain the vlans defined on that switch. This
prevents other vlans from passing traffic on trunk links.

If vtp is in use, then configure vtp pruning, which prevents unwanted
vlans to be propagated down the trunks.
