• PAP: Password Authentication Protocol as defined in RFC
1334. PAP is the simplest method for authentication. It involves
a two-way handshake where one peer sends a user name
and ID to another peer element in the network. The second
peer returns an authentication-acknowledge message either
accepting or rejecting the user name and password. When
selecting PAP, enter the password and ID at the bottom of
the configuration screen.
• CHAP: Challenge Handshake Authentication Protocol as de-
fined in RFC 1994. It involves a three-way handshake, in which
the test set sends a challenge containing its user name. The
server responses with a specific identifier expected for this
transaction. The test set then accepts or rejects this response,
when accepted the test set starts sending data.
• AUTO: Use this recommended setting to automatically detect
the authentication.
VPI
Range: 0 through 255
The default is 8, which is a typical Ethernet customer assign-
ment. Along with VCI, VPI identifies the next destination of a cell
as it moves through a series of ATM switches on the way to its
destination. The service provider typically assigns VPI.
VCI
Range: 0 through 65535
The default is 35, which is a typical Ethernet customer assign-
ment. Along with VPI, VCI identifies the next destination of a cell
as it moves through a series of ATM switches on the way to its
destination. The service provider typically assigns VCI.
IP ADDRESS
Options: STATIC (F1), DYNAMIC (F2)
• STATIC: This type of IP management means that the user has
a permanent IP address. For STATIC, enter the LOCAL IP; this
will be the value used during the test.
• DYNAMIC: This refers to dynamic IP management. If selected,
enter the IP address for the destination. Dynamic management
provides a way for computers to obtain protocol configura-
tion parameters (like the local IP address) dynamically from
the network. In this case, the IP address is not permanent to
the terminal; instead, the terminal requests an address from
the server on the network. When selecting DYNAMIC for IP
ADDRESS, the module sends a request to the server; the
server responds and provides an IP address. Upon select-
ing DYNAMIC, the LOCAL IP line disappears; the network
dynamically assigns an IP address.
