User's Manual

• When EAP-TLS is selected, the administrator is prompted to enter ID1.
• When Disabled mode is selected, the existing IDs and Passwords are erased.
Authorization
If 802.1x is configured and the IP Deskphone is physically connected to the network, the
IP Deskphone (supplicant) initiates 802.1x authentication by contacting the Layer 2/3 switch
(authenticator). The IP Deskphone also initiates 802.1x authentication after the Ethernet
connection (network interface only) is restored following a network link failure.
However, if the IP Deskphone resets, it assumes the Layer 2 link has remained in service and
is authenticated.
The IP Deskphone fails to authorize if the DeviceID and the IP Deskphone passwords do not
match the DeviceID and IP Deskphone passwords provisioned on the RADIUS Server. The
Layer 2 switch (authenticator) locks out the IP Deskphone and network access is denied. If
this happens during reauthorization, all phone services are lost. The connected PC operates
as normal.
Device ID
The Device ID is for use with the 802.1x (EAP) protocol. If the 802.1x (EAP) is not used, then
there is no prompt to enter the Device ID.
Password
The Password is for use with the 802.1x (EAP) protocol. If the 802.1x (EAP) is not used, there
is no prompt to enter the Password.
802.1ab Link Layer Discovery Protocol
802.1ab Link Layer Discovery Protocol (LLDP) is a standard for discovering the physical
topology between neighboring devices. 802.1ab LLDP defines a standard method for Ethernet
network devices, such as switches, routers, and IP Deskphones to advertise information about
themselves to other nodes on the network and to store the information they discover in a
Management Information Base (MIB).
802.1ab (LLDP) takes advantage of the VLAN Name and Network Policy TLVs, and provides
an automatic configuration of the IP Deskphone network policy parameters. Key parameters,
such as VLAN ID, L2 priority, and DSCP values are received from the switch and are
automatically configured in the IP Deskphone.
