Strange RX errors

(1/3) > >>

Hello,

I'm having a DGS-1100-08P in our trainings area. The switch powers an acccess point, a VoIP telephone and a camera.

The port connected to my AP shows lots of RX Errors (approx 20% of number of packets). Strangly, the uplink port to my DGS-1210-52MP shows the exact same number of RX Errors. Pinging the AP over some time shows no packet Drops. The DGS-1210-52MP shows also no errors.

I know RX errors are typically cable problems, but why do two ports show exactly the same number of RX errors?

Best regards,

Frank

FurryNutz:
Do the errors follow or continue if you change ports?
Do errors continue if you disconnect any of the devices?
What FW version if currently loaded?

eyermannf:
I'm running FW 1.0 (the only one I've found).

If I connect my AP to a different port, error follow. They stop if device is not connected.

Best regards,

Frank

FurryNutz:
And is the AP the only device causing these errors?

What happens if you factory reset this AP and set up the AP from scratch? What Mfr and model is this AP?
I presume you have swapped LAN cables with a different cable?

Hello,

AP is a Unify UAP-AC-Pro. I have 15 of this devices (same Firmware) deployed without any problems (but at other Switches). Haven't yet swapped AP.

I've swapped ports on the Switch (Port 5 and 6).

What I'm wondering is not the fact of RX Errors, it's the *same number* of RX Errors on two different ports (one to the AP, the other uplink). If there are some weird packets, shouldn't it be RX error on one port and TX on the other (however, can't Image what Kind of packets these could be :-)) My uplink switch shows no Errors for this port.

Best regards,

Frank
