I'm about to move several devices to another vlan. My question is this:
If I trunk a port for vlans 1 and 125, and if a device is connected to that port, yet we have NO clue what the device is or where it's at, it's still going to come in on vlan 1 if I can't specify on the device what vlan to use, correct? In order for me to tell it what vlan to use, I'd have to make that port an access port. Am I correct?
In other words, if I have a device on 10.125.125.50 and I trunk the port, yet I move the ip address 10.125.125.1 on the switch to the SVI, the device won't be able to see that SVI unless I tell it someway to come in on that new vlan, right?
I think i understand what you are getting at (sure you'll let me know if not !!)
I don't have anything to test on but the first thing is i don't think if you connect a single device to a port configured as a trunk port that you will get any connectivity.
If the port did come up then the device would send untagged packets and so these would be on the native vlan of the trunk port so that is the vlan they would come in on.
But as i say, never tried connecting non-trunking device to a trunk port.
