After s seconds
The maximum time that the link remains active in any one session. After this time, the link is
deactivated.
If it has been up for m minutes in a day
The router deactivates 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 deactivates 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
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 page. The router
uses this timeout until the PPP instance next deactivates only. After that, it uses the normal
timeout value.
If the link has not received any packets for s seconds
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 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 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 enabled, displays 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 amount of traffic that causes 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,
with the options of kilobytes, megabytes, gigabytes. For example, if the monthly tariff includes
up to 5 MB of data before excess usage charges are levied, it is useful to set this threshold to 4
MB. This would cause the router to create a warning entry in the event log once 4 MB of data is
transferred. You could use this event to trigger an email alert, SNMP trap, or SMS alert message.
