Hi there, I have a switch configured with a couple of vlans.
If I create a loopback interface on the switch and configure it with an ip from a vlan range, will I be able to ping from the switch using that loopback interface as a source (in order to mimick a ping coming from a real device plugged that switche's vlan?)
The problem is that I want to remotely ping out from the switch using that vlan, but there are no devices plugged into the switch vlan ports.

Thanks for any help.

You'll need to trunk each VLAN you want back to your host if you want to be inside of the same VLAN. That's the whole point of VLANs to keep things separate.

Otherwise you are routing from one network to another via Layer3.

In Linux it's pretty easy to setup multiple single or even double tagged VLANs and then bring up interfaces to ping out that particular VLAN as and when needed.

what type of switch are you using as this will decide on what you can and cant do.

Is the management IP of the switch on a different vlan? If not, just create a vlan interface on the vlan in question and chuck an IP on it. Throw in a default route and then ping away. 
Don't forget to add the vlan to the vlan DB.
This, of course, is assuming it's a cisco switch.
