Traffic entry?

Question

Network administration

There is an HP 1620-24G switch (I have never worked with such equipment, and even with vlan, too), it is managed, I am interested in the following:
If it has one port in vlan, and the rest will not (in switch mode), then that there will be no access from the network to this port, that is, you need to install another switch connected to this port?

Answer 1

in order not to install 1 more switch, "mark" several (how many) ports in another vlan
