Test 802.1x User Request Cause

Description

This scenario shows how to stop an 802.1x session using operational command supplicant disconnect. Accounting RADIUS stop messages should contain the following attribute: acct-terminate-cause=1.

Step 8: Ping IP address 192.168.100.1 from DUT1:

Note

Start packet capture in DUT2 to filter RADIUS stop messages (e.g., traffic dump monitor interface eth0 detail filter "udp port 1813" packets 1).

Note

Send a CoA/Disconnect request from the RADIUS server On Linux, the FreeRADIUS package includes the utility radtest that can be used to send these messages:

Show output
$ cat /osdx-tests/utils/dot1x/auth.req
User-Name = "testing"
$ radclient -s -t 1 -r 1 10.215.168.64:3799 disconnect coa_secret -f /osdx-tests/utils/dot1x/auth.req

Received Disconnect-ACK Id 11 from 10.215.168.64:3799 to 10.215.168.1:35147 length 44

Step 9: Run command interfaces ethernet eth1 802.1x authenticator show status at DUT0 and check if output contains the following tokens:

Current status: Unauthorized
Show output
Current status: Unauthorized

Note

Stop packet capture in DUT0 and expect the following RADIUS messages:
