110
The value in this textbox specifies the minimum period that the PPP interface should remain
available. This means that even if the link becomes inactive before this period expires, the
connection will remain open.
Close this interface
after s seconds
The value in this text box specifies the maximum time that the link will remain active in
any one session. After this time, the link will be deactivated.
If it has been up for m minutes in a day
The router will deactivate the PPP instance after it has been active for the value specified
in this text box.
If the link has been idle for s seconds
The router will deactivate this interface after the time specified in this text box if it
detects that the link has not passed any traffic for that period.
Alternative idle timer for static routes s seconds
The value in this text box specifies an alternative inactivity timeout for use in conjunction
with the “Make PPP n interface use the alternative idle timeout when this route becomes
available” parameter on the Configuration – Network > IP Routing/Forwarding >
Static Routes > Routes n > Advanced web page. This timeout will only be used until
the PPP instance next deactivates. After that the normal timeout value is used.
If the link has not received any packets for s seconds
The value in this text box specifies the amount of time that the router will wait without
receiving any PPP packets before disconnecting. The timer is reset with each received PPP
packet.
If the negotiation is not complete in s seconds
The value in this textbox specifies the maximum time (in seconds) allowed for the PPP
negotiation to complete. If negotiations have not completed within this period, the
interface is deactivated.
Generate an event after this interface has been up for m minutes
The value in this text box specifies the number of minutes (if any) after which the router
should create an event in the event log that states that the interface has been active for this
period.
Limit the data transmitted over this interface
When checked, this checkbox reveals the following parameters that control what data
volume restrictions (if any) should be applied to this interface:
Issue a warning event after n units
The value in this text box is the amount of traffic which will cause a warning event to be
generated in the event log stating that the specified amount of data has been
transferred. The units are specified by a drop-down list, having the following options;
KBytes, MBytes, GBytes. For example, if the monthly tariff includes up to 5MB of data
before excess useage charges are levied, it would be useful to set this threshold to 4MB.
This would cause the router to create a warning entry in the event log once 4MB of data
had been transferred. This event could then be used to trigger an email alert, SNMP trap
or SMS alert message.
Stop data from being transmitted after n units
The value in this text box specifies the total amount of data that may be transmitted by
this PPP instance before the link is blocked for further traffic, and the value in the drop-
down list specifies the units which are; KBytes, MBytes, GBytes.
