Hello,
I have used TekRadius with 802.1x client but my switch used as Authenticator does not correctly recognize "Tunnel-Type" and "Tunnel-Media-Type" returned from TekRadius.
As far as I investigated,
RFC 2868 says;
3.2. Tunnel-Medium-Type
Length 6
However, TekRadius sets length 7
Also,
3.1. Tunnel-Type
Length
Always 6.
However, TekRadius sets length 7.
Thus, my switch recognizes the value on the AVPs is set as zero.
Best regards,
Takeshi

Hi, Yasin,
Thakn you for quick fix. Unfortunately, the fix does not work.
Surely, the length is set to 6 in the latest code 2.8. However, the value is still set in 7th octet although the longth is set to 6.
Here is the sniffer trace sent from TekRadius.
You will see Tunnel-Type is set to zero. Actually, I set VLAN (13). See the Hex dump below. You will see 13 (0xd) is set in 7th octet.
Attribute Value Pairs
AVP: l=6 t=Tunnel-Type(64) Tag=0x01: Unknown(0)
Tag: 0x01
Tunnel-Type: Unknown (0)
[Not enough room in packet for AVP]

Hi,
Thank you!
I have downloaded. But the behavior has been back to previous one. So, lenght is set to 7.
The file size of "Setup"' is 459,264 byte and it is created on 17/Oct 10:37:02 as far as I see a property of the file on Windows.
I think I am using correct file.
Could you please look into that?
Best regards,
Takeshi
