GS110EMX - 2 VLAN from the same switch: Loop issue?
Hi folks, I'm opening this discussion to be sure I'm not doing anything wrong. Long story short, my TV setupbox must be directly connected to the internet box due to my ISP's constraints 😒. Un...
Let’s say it is a creative use of VLANs.
You got you untagged/tagged and PVID 100% correct. However I think you are not correct on these two counts.
1. “my TV setupbox must be directly connected to the internet box due to my ISP's constraints”
2. “it appears that both VLANs are well isolated.”
The reason for this is that your final configuration is still a single subnet flat network. If your TV works in this setup, it should also work without those VLANs. Also, there is no isolation there since you have bridged the two VLANs with the hub. The only advantage I can see from that setup is that you can use two links between the top switch and the hub without creating a loop.
Anyone to confirm that this configuration is allowed and licit? 🙏😢
