Hello Usman

There are several concepts by different vendors that use the abbreviation VSI. When it comes to Cisco, this is a Virtual Switch Interface. It was used with the old BPX multiservice switches. These are over 20 years old, so you’re probably not talking about this. But because I found it interesting, I decided to upload a datasheet from 1999 for the BPX 8600:
technicheskie-kharakteristiki-kommutatori-cisco-bpx-8600-series-multiservice-switches.pdf (329.6 KB)
Virtual Switch Interface Protocol was used with these switches for MPLS, and you can find out more about that here.

However, I believe you are talking about the VSIs used in H3C routers or Huawei devices.

Can you clarify what particular feature you are looking to learn more about?

I hope this has been helpful!
