VLAN question on factory default setting
I have a XS716T with 3 VLANS. Ports 1-5 on VLAN 2, 6-10 on VLAN 3, 11-15 on VLAN 4, and port 16 is the trunk port. The management VLAN is VLAN 4. I don't have a default VLAN 1 on this switch. Everyth...

So I connected this switch to port 13 on the XS716T. Then I connected a laptop to the XS728T. I was not expecting to get a VLAN 4 ip, but I got one.
Why is this? The XS728T only have VLAN 1 in it, and it's on factory setting.
Simple: You have connected the new switch to a port associated to the untagged VLAN 4. There is no "magic" to discover that this port is a member of the VLAN, anything you connect there does see a "flat" L2 network - this VLAN 4. On the newly added switch all ports default to VLAN 1 untagged - so a flat network again. Compare: The same thing would happen if adding an unmanaged switch btw.
On a static VLAN configuration, there is no automatic distribution of VLANs going on - and this can't happen on an untagged port anyway.

This is what my configuration looks like on the XS716T

I'm assuming the XS728T is acting as a "dummy" switch and that's why it's getting VLAN 4?
I looked at this Netgear article, and that's how I have my switch setup, except I don't have VLAN 1
