if it has been up for n minutes in a day
The maximum time that this ISDN interface may remain connected during any one day. After
this time, the ISDN link is deactivated.
If the link has been idle for n seconds
The ISDN interface closes the connection if the link is inactive for the length of time specified
by this parameter.
Alternative idle timer for static routes n seconds
An alternative Inactivity timeout for use in conjunction with the Use 2nd inactivity timeout
when this route becomes available parameter on the
Configuration > Routing > Routing >
Static Route n
pages. This timeout will only be used until the PPP next deactivates. After that,
the normal timeout value is used.
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
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 amount of time that the router waits 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 checked, this checkbox enables 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 which 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, having the following options;
KBytes
,
MBytes
,
GBytes
. For example, if the monthly
tariff includes up to 5MB of data before excess usage 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.
