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?
No, I understand that part. I have the following situation:
If I have 2 vlans (1, 125) and the native is 1, and I can't tell the device WHAT vlan to go out on other than making that device an access port, yet it NEEDS to be on that VLAN, because I haven't told the device that "you're connected to vlan125", it's going to go out on one. And if that device's IP is on the vlan125 subnet, then it won't see it until the port is converted to an access port of vlan125 or I tell the device that it's a member of that vlan.
Not exactly. I don't know how to explain it by typing.
Let's try this:
Camera: 10.100.100.50 GW: 10.100.100.1
Switchport for camera is NOT an access port
Switch SVI: VLAN100:10.100.100.1
Since I didn't configure the camera's port as an access port, and I didn't configure the camera to be a certain vlan, won't the camera go out as VLAN 1? It won't even be able to see the SVI on the switch even if it's a trunked port because it's tagging its traffic as UNTAGGED because it has no clue that the address moved, right?
