L3 Vlan interface

david-flores · ‎01-29-2010

I am working in a lab environment and I have created several vlan intefaces on my 3560 that I want to be protocol "up". I only have 1 router connected to it for 1 vlan only that is currently protocol up, is there a command that I can use to have all the other vlans protocol up, so I can ping them? Please advise.

thanks.

If you want the other vlan interfaces to be up/up and you have no devices to connect into the switch ports then the only way to do this would be to make the link between the 3560 and the router a trunk link and allow all the vlans on that trunk.

that what I figured. Thanks Jon. I was hoping there was some other trick using loopback interfaces, or tweaking the keep-alives.

thanks again.
