HELP creating VLAN between C3750G and C6509

Unanswered Question
Mar 12th, 2007

I have a VMware-based network I want to VLAN off from my regular network. It sits behind a C3750G switch. I also need it to trunk over to my C6509 switch which has an older IOS (v6.3(1)). So far, nothing I've tried has been successful, bith trunking and VLANs.

Can someone post the commands or config I need for each switch to successfully create the VLAN between the switches?


I have this problem too.

First determime which switch is acting as a VTP server.Assuming u r 6509 to be vtp server configure u r 3750 as a vtp client.

connect a link from u r 6509 to 3750 and configure it as a trunk link.

on 6509 if u r having catos then u can configure like this

set trunk mod/port on dot1q/ISL

and on IOS

go int the interface mode

conf t

interface interfacename

switchport mode trunk

switch port trunk encapsulation dot1q/isl
