Eap Termination - HP MSR Series Configuration Manual

10. Upon receiving the RADIUS Access-Accept packet, the access device performs the following
operations:
a. Sends an EAP-Success packet to the client.
b. Sets the controlled port in authorized state.
The client can access the network.
11. After the client comes online, the access device periodically sends handshake requests to
check whether the client is still online. By default, if two consecutive handshake attempts fail,
the device logs off the client.
12. Upon receiving a handshake request, the client returns a response. If the client fails to return a
response after a number of consecutive handshake attempts (two by default), the access
device logs off the client. This handshake mechanism enables timely release of the network
resources used by 802.1X users who have abnormally gone offline.
13. The client can also send an EAPOL-Logoff packet to ask the access device for a logoff.
14. In response to the EAPOL-Logoff packet, the access device changes the status of the
controlled port from authorized to unauthorized. Then, the access device sends an EAP-Failure
packet to the client.
