Unable to configure Virtual Link for VSS

[CiscoBrownBelt]

So I understand the the port-channel to be the virtual link should not be a switchport or trunk or have an IP.

So the only way I can get the switch virtual link 1 command to take is if I do "switchport" command first which in turn will show a trunk configuration under the port-channel as well. Here is the error. Anyone know what I may be doing wrong?

switch virtual link 1
Interface Po100 is a Layer 3 interface.
Convert it to a Layer 2 switchport before
configuring it as a VSL Port-channel.

Not sure .. try 'switchport' under interface may be?

conf t

interface Po100

switchport

I did that, but each time I do that, it will configure the port as a trunk as well.

What switch platform are you using?

here is a sample working config

interface Port-channel xx
switchport
switchport mode trunk
switchport nonegotiate
switch virtual link x

I am using WS-C4510R+E

Ok so yes what you showed is the only it seems to let me do it. Ok I guess I will continue with that and see what happens.

Think additional parameters such as dual-active detection pagp trust channel-group group_number is necessary?
