A user’s Junos Pulse client uses 802.1X to access a wired network and is failing to authenticate.
You run a packet capture from the user’s PC and notice that immediately after the client machine
sends an EAPoL-start packet, an EAP-failure packet is returned. You review the RADIUS
troubleshooting logs on the MAG Series device and do not see any authentication attempts from
the user. Other users on the same Ethernet switch are successfully authenticating.
Which device is sending the EAP-failure packet to the workstation?
A.
The RADIUS server
B.
The EAPoL server
C.
The workstation’s network adapter
D.
The Ethernet switch
