Chapter 6: Configuring PPP Sessions

Information

Description

 

 

Connection Name

A unique descriptive identifier of the session that also displays in the connection

 

field.

ATM VPI

Virtual Path Identifier (VPI) identifies the virtual path that transports ATM cells in a

 

virtual Channel. The range of values is 0 to 15.

ATM VCI

Virtual Channel Idenifier (VCI) identifies a virtual channel for each session (each

 

session is a virtual channel). Can be a number from 32 up to a maximum of 253 (on

 

VPI 0, VCIs 254 and 255 are reserved), with the first 32 (0 through 31) reserved.

Login Name

Each session requires a Logon Name that is supplied by the service provider.

Login Password

Each session requires a Logon Password that is supplied by the service provider.

Primary DNS

IP address of Domain Name Service device that translates names into numeric IP

 

addresses. This is the device at the service provider that the modem will translate

 

requests.

Secondary DNS

IP address of a secondary Domain Name System device that translates names into

 

numeric IP addresses.

Address Translation

Enables/disables the use of Network Address Translation (NAT) protocol to translate

 

private IP addresses to public IP addresses assigned to each session.

InBound NAT Default

IP address of the designated NAT default user for inbound traffic. When the NAT

 

engine does not have enough information to do the inbound translation, it forwards

 

the inbound packet to the NAT default user.

Continuous Retry

Enables/disables the Continuous Retry function of the PPP session establishment

 

process. When Continuous Retry is enabled, the PPP engine continuously retries

 

establishing the PPP session until one of the following is true:

 

The PPP session is established successfully. The session status then goes to the

 

UP state.

 

Authentication fails during the handshaking. The session status then goes to the

 

LogInErr state.

 

The PPP session is disconnected. The session status then goes to the DOWN

 

state.

Always ON

When enabled, the PPP engine establishes/maintains the session even when there

 

are no users assigned to it. When disabled, the PPP engine will not establish or will

 

terminate the session when there are no users assigned to it.

Session Enable

If enabled, the session is active and is ready to establish the PPP link. If disabled, the

 

session is not active.

Address Assignment

Determines whether the session IP address is assigned by the service provider

 

(Dynamic) or entered by the user (Fixed).
