Iif you just want to bridge the VLANs.. I.E. make them as one:<br />
<br />
On one switch:<br />
<br />
int Fa0/1<br />
&nbsp;switchport access vlan 20<br />
&nbsp;switchport trunk encapsulation dot1q<br />
&nbsp;switchport mode access <br />
<br />
Other switch:<br />
<br />
int Fa0/2<br />
&nbsp;switchport access vlan 40<br />
&nbsp;switchport trunk encapsulation dot1q<br />
&nbsp;switchport mode access<br />
<br />
Plug the ports together.<br />
<br />
Voila, kinda defies the point of having VLANs though...<br />

On one switch:

 switchport access vlan 20
 switchport trunk encapsulation dot1q
 switchport mode access

Other switch:

int Fa0/2
 switchport access vlan 40
 switchport trunk encapsulation dot1q
 switchport mode access

Plug the ports together.

Howdy,<br />
&nbsp; This question is kind of off the wall but curiosity is kicking in here. Is it possible on a Cisco c3750 switch or any higher switch to create a tunnel between two vlans say vlan 20 to vlan 40? I know you can create Tunnels between routers. I was just wondering if it's possible to create that virtual connection between two vlans.<br />
<br />
Hope this makes sense..

Tunneling vlans

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.

Networking

Networking software modules are interfaced with a framework implemented on the machine's operating system that implements the networking functionality of the operating system. The best known frameworks are the TCP/IP model and the OSI model. Systems typically do not use a single protocol to handle a transmission. Instead they use a set of cooperating protocols, sometimes called a protocol family or protocol suite.[9] Some of the best known protocol suites include: IPX/SPX, X.25, AX.25, AppleTalk and TCP/IP. Other protocols indirectly related to networking include the hypertext transfer protocol (HTTP) and its related technologies, Dynamic Host Configuration Protocol (DHCP), Domain Name Server (DNS) and other Internet protocols.
