How to set up a reset switch behind another switch and vlan?

Question

Computer networks

There are three switches:

No. 1 Office → No. 2 Pass-through switch → No. 3 End subscriber switch
100 vlan are registered on all switches.

Such a situation, switch No. 3 was reset to the factory settings, respectively, it now has 1 vlan.
The question is how now to go to it remotely and reconfigure it? Since he now has 1 vlan, I don’t see him and can’t access him.

I now need to add vlan 1 to the trunk ports of switch #2 and the trunk port of switch #1, as well as to one of the ethernet ports of switch #1 from which I will already configure switch #3 ???

In general, how to send vlan 1 to switches No. 1 and No. 2 so that I can remotely see switch No. 3)

Answer 1

Vlan 1 is added to the trunk port on switches 1 and 2. That is, on switch port one towards switch two, vlan 1 and vlan 100 must be configured. Also on switch two towards switch one must be vlan 1 and vlan 100. And on On the second switch towards the third switch, the acces port with vlan 1 should be configured. After resetting on switch three, in theory, all ports are acces and vlan 1.

Answer 2

What about switches?
