It could be, so far reports have just shown downgrading to 1.5.3 and back to 1.5.5 fixes it. This doesn't make much sense to me as to how that works yet. But I suspect the act of downgrading and re-upgrading is somehow affecting the status of the switchcore for VLANs.
It's worth trying on a switch to see if it helps. If you try it, please let me know what you're results are here.
Thank you for your dedication and the quick reply! :) After some review of v1.5.4 references, it looks like that was mainly a hardware support release, so it would logically be equivalent to v1.5.3 on this issue.
Also, we mostly went to those versions as general practice of staying current. We have done no VLAN updates on any of the v1.5.5 switches, so would not have seen the new issue.
As disruptive as large VLAN changes can be on production networks, our intent now will be to stabilize everything at v1.5.4 and begin the changes. I will let you know right away on the slim chance I see this VLAN problem. Then we'll let our network stabilize before testing v1.5.5 or possibly a fix version you might have by then.
