Straight up answer would be Firewall.

Switches are used to forward traffic based on the source and destination mac-address. Unless you have a L3 Switch.

If you want to permit an incoming connection, you'd need to use your firewall to perform such action.
If you have a cisco router, the regular configuration would be "IP nat inside source static tcp 192.168.1.5 443 200.200.200.2 443"

Cheers,

Thanks for the reply.

Yes I have L3 switch. Can I do it the switch or firewall. Currently

Port 40 is in the server vlan?
Hemil AquinoNetwork EngineerCommented:
You can't do it in the switch, switches do not perform any type of nat.
You need to create the rule in your firewall.

When you say port 40, are you referring to the switch port? or vlan 40?

Is a switch port.

Currently a new socket connected to port 40 in the TOP switch. Vendor required to open port 443 and allow access Internet.

Is there any good documentation how to open 443 port in firewall and router to allow internet access?

Correct it should be both side.
Hemil AquinoNetwork EngineerCommented:
I think you need to elaborate with more details your question, its kind of ambiguous.

1- What exactly is connected into the port 40?

2- When you say the vendor require port 443 and allow internet access, are you saying you dont have internet, and the vendor of such app  wants you to open the port 443?

3- what type of firewall do you have?

4- Do you have any knowledge of your appliance?

Is a Cato socket connected to switch port 40.

But required  to open up port 443 firewall and router ?
Hemil AquinoNetwork EngineerCommented:
I dont know about "Cato Socket"
But in order for you to open the port you need to do it in your firewall.

You forgot to tell me what firewall model you have?

You would be opening the port at the firewall level, not the switch.

Here is an old EE question that gives how to open ports in ASDM: https://www.experts-exchange.com/questions/26698237/How-to-open-ports-on-a-Cisco-asa-5510-using-ASDM.html

Since this topic is up, it would be clearer if you mentioned exactly what got requested. Sometimes vendors will word things in a strange way, but all they really require is that you allow OUTBOUND traffic over certain ports.
