The PPP may have up to 64 entries, containing the following values:
Everything OK? Checking the line with LCP
The devices involved in the establishment of a connection through PPP negotiate a
common behavior during data transfer. For example, they first decide whether a
connection can be made at all using the security procedure, names and passwords
specified.
The reliability of the line can be constantly monitored using the LCP once the connection
has been established. This is achieved within the protocol by the LCP echo request and
the associated LCP echo reply. The LCP echo request is a query in the form of a data
packet which is transferred to the remote station along with the data. The connection is
In this column of the
PPP list...
...enter the following values:
Device-name Name the remote station uses to identify itself to your router
Auth. Security method used on the PPP connection ('PAP', 'CHAP' or
'none'). Your own router demands that the remote station
observes this procedure. Not the other way round.
This means that 'PAP' or 'CHAP' security is not useful when
connecting to Internet service providers, who may not wish to
provide a password. Select 'none' as the security attribute for
connections such as these.
Key Password transferred by your router to the remote station (if
demanded).
A string of asterisks (*) in the list indicates that an entry is
present.
Time Time between two checks of the connection with LCP. This is
specified in multiple of 10 seconds (i.e. 2 for 20 seconds).
Simultaneously the time between two checks of the connection
according to CHAP. This time is entered in minutes.
The time must be set to '0' for remote stations using Windows 95,
Windows 98 or Windows NT.
Try Number of retries for the check attempt. You can eliminate the
effect of short-term line interference by selecting multiple retries.
The connection will only be dropped if all attempts are
unsuccessful. The time interval between two retries is 1/10 of
the time interval between two checks.
Simultaneously the number of the “Configure requests” that the
router maximum sends before it assumes a line error and clears
the connection itself.
Conf, Fail, Term These parameters are used to affect the way in which PPP is
implemented. The parameters are defined in RFC 1661 and are
not described in greater detail here. You will find troubleshooting
instructions in this RFC in connection with the router's PPP
statistics if you are unable to establish any PPP connections.
The default settings should generally suffice.
These parameters can only be modified via SNMP or TFTP (using
ELSA LANconfig
)!
Username The name with which your router logs onto the remote station.
The device name of your router is used if nothing is specified
here.
