Hi,

I have a big struggle with my X-mas gift (SG3428XPP-M2) which should replace my zyxel poe switch

so i had everything connected to my zyxel and added the SG3428XPP-M2 it was detected and adopted. But if I try to plug the oc200 to the SG3428XPP-M2 I loose connction/lock myself out

the zyxel has set PVID to 144 as this is my main/mgmt VLAN.

if I try this on the SG3428XPP-M2 im always cutting the branche im sitting on and lock myself out

what is the correct procedure to make VLAN 144 the mgmt VLAN for the switch and make it work with the oc200?

I feel like I missed some tiny but important detail and this makes me faining over and over again
