    High RxBadPkt on TL-SG108E

    Model : TL-SG108E

    Hardware Version : V1

    Firmware Version : 1.1.2 Build 20141017 Rel. 50749

    ISP : [/COLOR]

    I'm getting very high RxBadPkt on ports configured as VLAN access port. Setup is Router - Cisco switch - TP-Link01 - TP-Link02. Cisco shows no errors or dropped packages. On the trunk ports (Tagged) of the TP-link switches the RXBadPkt is the total count of the RxBadPkt packages connected to a configured access port ( Untagged 802.1Q PVID). Connecting the same device (laptop or AP) to a port without a configured PVID (so default PVID1) on either switch the RxBadPkt is 0 and stays 0. I'm not noticing bad performance on the access ports but the high RxBadPkt seems really strange. What could be the cause of this?

    Configuration of the second TP-Link switch with a connected access point on port 8 with configured VLAN:

    Configuration of the first switch:

    Now monitoring the statistics shows a lot of RxBadPkt when Access Point is connected to VLAN on port 8 (Monitoring was refreshed shortly before screenshot):

    Same on switch 01:

    Connecting access point (or whatever device) to a port without a configured VLAN shows no RxBadPkt. In this case connected to port 5 on switch 1. Same result on switch 2. The same device on a configured VLAN and the RxBadPkt sky rockets very quickly.
