PPP Logs
This section describes the WAN PPP connection logs. The PPP type can be configured from the
web management.
PPPoE Idle-Timeout Logs.
Explanation The Logs suggest that the fail-over was detected after 5 attempts instead of 3.
However, the reason the messages appear as above is because of the WAN
state transition logic which is part of the failover algorithm. The above logs can
be interpreted as below. The primary link failure is properly detected after the
3rd attempt. Thereafter the algorithm attempts to restart WAN and checks once
again to see if WAN1 is still down. This results in the 4th failure detection
message. If it is then it starts secondary link and once secondary link is up,
secondary link is marked as active. Meanwhile secondary link has failed once
more and that results 5th failure detection message. Please note that the 5th
failure detection and the message suggesting secondary link is active have the
same timestamp and so they happen in the same algorithm state-machine
cycle. So although it appears that the failover did not happen immediately after
3 failures, internally, the failover process is triggered after the 3rd failure and
transition to secondary link is completed by the 5th failure. The primary link is
also restarted every 3 failures till it is functional again. In the above log, primary
link was restarted after the 6th failure i.e. 3 failures after the failover process
was triggered.
Recommended Action Check the WAN settings and WAN failure detection method configured for the
primary link.
