on the RADIUS server or the terminal has an
incorrect identity (bad login and/or password).
802.1x Auth Success
802.1x authentication process is complete. The
RADIUS server grants access to the terminal, the
authenticator opens its port.

Ethernet link
By default, the IP Touch 4018EE phone is configured to perform auto-negotiation on both ports
(LAN and PC). Provided that the PC and the LAN switch are also configured to perform auto-
negotiation, this is the best configuration for QoS improvement.
However, depending on the network configuration, it may not always be possible to leave the
terminal in auto-negotiation: link speed and duplex of both ports can be forced to determined
values using the supervisor menu:
1- Plug in the set
2- Once the set displays initialization, press the “i” key, then the “#” key or enter the
admin settings during phone idle status
3- Use the navigation key to select Ethernet Links
4- Modify data as requested
A configuration mismatch between the terminal and PC/LAN switch can lead to nasty effects on
the voice quality:
– No link (or speed mismatch): 8, 9, 11 and 12
– Packet loss (or duplex mismatch): 2, 4, 7 and 14
Note 1: collisions are not detected by the device operating in full-duplex mode: packets from this
device are never re-transmitted if a collision occurs on them.
The following table lists all possible Ethernet port configuration combinations when connecting
an IP Touch set to an external device (switch on LAN side, PC on PC side). For each combination,
the table shows the link status: valid or invalid (duplex or speed mismatch), as described above.
