Issue a warning event after n Kbytes/Mbytes/GBytes
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 5 MB of data before excess usage charges are
levied, it would be 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 had been transferred. You could use this event
to trigger an email alert, SNMP trap or SMS alert message.
Stop data from being transmitted after n Kbytes/Mbytes/GBytes
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

received
Reset this interface if n packets are transmitted and the connection has been up for at least
s seconds

number of packets text box has a value greater than 0, the router will reset the link if that many
IP packets have been transmitted but none have been received, and the link has been active for
at least the value specified in the second text box.
Reboot the router after n consecutive resets
If the value in this text box is non-zero, the router reboots if the PPP link has been reset the
specified number of times as a consequence of the value n packets (described above) being
