Administering Telephone Options

transmitting a response that did not contain an identity or a password, an 802.1X Failure interrupt screen is displayed.

When a telephone is installed for the first time and 802.1x is in effect, the dynamic address process prompts the installer to enter the Supplicant identity and password. The IP telephone does not accept null value passwords. See “Dynamic Addressing Process” in the Avaya one-X™ Deskphone Edition for 9600 Series SIP IP Telephones Installation and Maintenance Guide. The telephone stores 802.1X credentials when successful authentication is achieved. Post-installation authentication attempts occur using the stored 802.1X credentials, without prompting the user for ID and password entry.

An IP telephone can support several different 802.1X authentication scenarios, depending on the capabilities of the Ethernet data switch to which it is connected. Some switches may authenticate only a single device per switch port. This is known as single-supplicant or port-based operation. These switches typically send multicast 802.1X packets to authenticating devices.

These switches support the following three scenarios:

●Standalone telephone (Telephone Only Authenticates) - When the telephone is configured for Supplicant Mode (DOT1X=2), the telephone can support authentication from the switch.

●Telephone with attached PC (Telephone Only Authenticates) - When the telephone is configured for Supplicant Mode (DOT1X=2), the telephone can support authentication from the switch. The attached PC in this scenario gains access to the network without being authenticated.

●Telephone with attached PC (PC Only Authenticates) - When the telephone is configured for Pass-Through Mode or Pass-Through Mode with Logoff (DOT1X=0 or 1), an attached PC running 802.1X supplicant software can be authenticated by the data switch. The telephone in this scenario gains access to the network without being authenticated.

Some switches support authentication of multiple devices connected through a single switch port. This is known as multi-supplicant or MAC-based operation. These switches typically send unicast 802.1X packets to authenticating devices. These switches support the following two scenarios:

●Standalone telephone (Telephone Only Authenticates) - When the telephone is configured for Supplicant Mode (DOT1X=2), the telephone can support authentication from the switch. When DOT1X is "0" or "1" the telephone is unable to authenticate with the switch.

●Telephone and PC Dual Authentication - Both the telephone and the connected PC can support 802.1X authentication from the switch. The telephone may be configured for Pass-Through Mode or Pass-Through Mode with Logoff (DOT1X=0 or 1). The attached PC must be running 802.1X supplicant software.
