Hi,

 

i just tried to set up 802.1x with MAB on my T2600G-18TS. The client authenticates fine on the radius server and is connecting to the network. But i get a constant packetloss of about 5-10%. When i switch off 802.1x on that port it's immediately fine again. When i turn it back on, packets keep getting dropped.

I tried different client devices and i tried to ping different targets. All the targets i tried are connected to the same switch as the client so no other hardware is at play here.

 

i did a tcpdump on the target device and the dropped pings don't even reach it.

 

i did a complete config reset and just set up 802.1x with MAB again on the switch to make sure i didn't mess up something else but still the same problem

 

any idea what could cause this?

You can upgrade the new formware for T2600G-18TS. When you meet the issue, make sure the client already change to authorized status on T2600G-18TS.

@Andone I can't find any newer firmware for this device.

 

The client is shown as "authorized" in the web inte
