Thanks but I have expected multiple troubleshoot scenarios
what scenarios you are looking for?
How do I test for jitter and packet loss ? I there a free app o can use on windows ?
you can use iperf3, but this needs to be done between 2 hosts. using mtr or icmp, you can record the packets and load it into wireshark to check jitter...
good explanation but it would have been very helpful if you would have labeled the links
sure, i should. will do next time
Reading the cisco SG book for this chapter and what I got is more more than confusion. I have to say a good demonstration is better than a thousand papers or articles. Well, from the prospective of engineers not researchers LOL
Thanks :)
Really Great tutorial for understanding P and Q Space with TI-LFA
Perfect mate
Perfect and simple explanation.. thanks Guan for making my life easy
you welcome, i thought sharing it before i forget what i did is also valuable for my self and the others
Very useful mini guide, thank you.
by the way, the udp packet that the sender generates, they increments for both source and destination port. In this way the ECMP equal cost multi-path are tested throughout the trace. However, sometime one wants to test the exact network path, ignoring the ECMP. For this to happen, one can use for example lft : "lft -T -u -z 62.52.30.84" to test the network by fixing the destination port. Unfortunately i haven't found a program that enables you to also fix the source port. But the lft command should be to do the job. Enjoy!
