Hello all!
I am trying to configure SAA so that when I have an outage on a path, a traceroute is triggered that stores hops in history and therefore records exactly where the outage occured.
At the moment, I am doing some testing to see if this is possible. When the IP address the SAA PathEcho probe is monitoring is reachable, I can record the hops in the history. However, when the IP address is not reachable, no history is recorded! A debug IP Packet also shows that the PathEcho probe does not seem to timeout - it seems to keep sending packets beyond the life of the probe, which for testing purposes I have at 60 seconds..
An example config I am using is shown below and I've shown the results when the IP address is up: Am I missing anything to be able to record history when the destination IP is down/unreachable?
Many thanks in advance!
