Hello @TK_Liew,
I can confirm what @rkuiken is seeing in Firmware 7.1.1 GA, the Trunk Custom options have gone missing on the Balance 380 & the Balance 580 & the MediaFast 500.
I’ve not checked all of the range yet, I will leave that to the Peplink engineers.
We’ve been discussing Custom VLANs in the Trunk within another thread.
Fortunately for our clients at each of there sites we have another managed switch, though this could be an issue for several others out there. What is the ETA until the next release will be available to restore this feature?
Happy to Help,
Marcus
