We are using the PTP550s to connect Cisco switches (Series 9000, 2960X) as trunks links. However, not all VLANs work well. Do these PTP550s support the 802.1Q protocol?
When describing a problem, always report firmware's version you're using.
I think that was an ooooold bug with ooooold firmware. I hope...
Hi, I have the same problem, did you found the solution?
