PPP-list

Parameter settings for PPP connections

The router needs the device names contained in the PPP list in order to determine the security procedure settings suitable for the connection and to determine the PPP parameters. It contains a maximum of 64 entries and is structured as follows:

Device-name Auth. Key Time Try Conf Fail Term User-name
GLASGOW CHAP ******* 0 5 10 5 2 ELSA

Not all parameters can be reached via the Telnet configuration. Use ELSA LANconfig so far as possible.

Below is a detailed description of the meaning of each field:

Device-name In the Device-name column, you can enter the name with which the remote station logs onto the router. Entries are not case-sensitive!
Auth. In this column, you can enter the security procedure to be used for verification of the remote station. Default: PAP

none The router does not negotiate authentication with the remote station when establishing a connection. However, the remote station can itself require authentication from the router.

PAP The remote station is checked as per the Password Authentication Protocol

CHAP The remote station is checked as per the Challenge Handshake Authentication Protocol
Key A password may be entered in this column. Its presence is indicated by the symbol * and it is used to check the remote station. It may consist of 95 characters (7-bit ASCII, including spaces). Default: None The set ? command shows a list of the allowable characters.
Time In this column, you can enter the period of time between two remote station verifications specified in minutes. The CHAP protocol must be set here. Default: 0
Try In this column, you can specify the number of times the verification attempt is to be repeated. If verification fails, the connection is immediately terminated. Default: 5
Conf, Fail and Term These parameters may be used to influence the operation of the PPP. They are defined and described in RFC 1661. The default values are sufficient for most remote stations. If nothing is entered here, the values 0,0,0 appear in the display but the default values 10, 5, 2 are still used. These parameters can only be changed via SNMP or TFTP (using the ELSA LANconfig configuration program)!
User-name The user name (max. 64 characters) transmitted to the remote station during PPP negotiation. The router identifies itself to the remote station with it. If no user name is entered, the device name serves as the user name. Entries are case-sensitive here.
