Allowing single port to communicate with multiple VLANs on Cisco SG350-28

[Tuhi]

Hi,

I have a Cisco SG350-28 switch with me. The requirement here is to connect 4 PLC devices and a computer device (server) on the switch.

However, I only want the server to be able to communicate to these 4 devices and these 4 ports on which these PLC devices are connected should not be able to communicate with each other.

In nutshell, if from port 1-4, PLC devices are connected and on 5th port server device is connected then traffic should be allowed as below: -

1) 1 <-> 5

2) 2 <-> 5

3) 3 <-> 5

4) 4 <-> 5

Below traffic should not be allowed : -

1) 1 <->2/3/4

2) 2 <->1/3/4

3) 3 <->1/2/4

4) 4 <->1/2/3

Please suggest how to configure the switch to achieve this configuration.

                - Is it questioning  broadcasting-time , or do you want to stay real ?

Didn't get your question regarding broadcasting-time.

The communication should happen in real time only.

 - Actually I need to apologize for these remarks, guess my morning coffee was from a bad brand, I confused the group-name , with your username. Apologies again, will look into your question.

That's okay. Looking forward for suggestions

 - You may want to use private vlan(s) for this - have a look at this document :
