Authorization; Device Id; Password; Dhcp - Nortel 1120E Administration Manual

Authorization

If 802.1x is configured and the IP Phone 1120E is physically connected to
the network, the IP Phone 1120E (supplicant) initiates 802.1x authentication
by contacting the Layer 2/3 switch (authenticator). The IP Phone 1120E
also initiates 802.1x authentication after the Ethernet connection (network
interface only) is restored following a network link failure.
However, if the IP Phone 1120E resets, it assumes the Layer 2 link has
remained in service and is authenticated.
The IP Phone 1120E fails to authorize if the DeviceID and the IP Phone
1120E passwords do not match the DeviceID and IP Phone 1120E
passwords provisioned on the RADIUS Server. The Layer 2 switch
(authenticator) locks out the IP Phone 1120E and network access is denied.
If this happens during reauthorization, all telephone 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.

DHCP

There are three methods of provisioning DHCP.
1. No DHCP (Manual configuration): All the Device Settings parameters
2. Partial DHCP: The IP Phone 1120E with SIP Firmware is configured to
3. Full DHCP: The IP Phone 1120E with SIP Firmware is configured to get

NO DHCP mode

No DHCP mode is also known as Manual Device Settings. In this mode, the
IP Phone 1120E does not need a DHCP server because no DHCP requests
are sent during startup. All necessary parameters must be configured
manually or through the device configuration file.
The minimum following parameters must be configured to achieve normal
operation:
