On the port-miror port, its adding an errant 802.1Q vlan tag header on the outbound direction only.  On the actual port itself, there is no tagging, but on the port-mirror port outbound packets are tagged, but inbound packets are not.  Vendor acknowledges the bug, but says its in the asic and cannot be fixed.\r\n\r\nIs there a way to tell ntopng to ignore vlan tags?  the ports themselves are in access mode on the switch and are all the same vlan, but when port-mirroring adds the tag, ntopng splits sending and recieving into 2 separate hosts...\r\n\r\n192.168.99.99 for recieve\r\n192.168.99.99@10 for send\r\n\r\nits not ntopnng's fault, its flagging correct, but the fault lies totally on my crappy core switch that wont get replaced any time soon!"}}
