Uplinks and VLANs

Darvin — Thu, 22 May 2025 06:35:06 GMT

Hello friends
I need your help configuring three ExtremeSwitching 220-48t-10GE4 (Software Version 1.2.6.9). I want to do it through gui if possible. At this moment I am configuring one switch. My assumptions:
- of course I want to use uplinks ports 1/0/49 and 1/0/50 10GbE SFP+ . My diagram (A<>B<>C<>A).
- I want to use three VLANs and one VLAN as a black hole. At least chatgpt says I need it.

My initial setup looks like this (attachments). For now, I want to put everything into VLAN 10.

I have many questions and a few problems :).

1) I go to Switching > VLAN > Port Configuration, change to VLAN 10, go to port 49 or port 50 and set the Tagging option to Tagged, and then it changes to Untagged?
2) I go to Switching > VLAN > Port Summary. Should VLAN999 (blackhole) be set for all ports in Forbidden VLANs? Or just for ports 1/0/49 and 1/0/50 as in my configuration?

Please help 🙂
