How to Bandwidth speed test on cisco sdwan catalyst 8500

[KingsQ]

Hi,

can anyone let me know how to do the bandwidth speed test for cisco sdwan catalyst 8k models on CLI

Hi @KingsQ,

You should be able to navigate to the Speed Test functionality from within the Cisco Catalyst SD-WAN Manager (formerly vManage) by going to 'Monitor' > 'Devices'.

Once you are on the 'Monitor • Devices' screen, choose the device you want to run a speedtest on by clicking the 'three dots' on the right-most column of the screen next to your chosen device. From there, it should drop down a list of options where you can choose 'speedtest'. If it does not drop down a list of options, it will be because of the viewport width of your browser (determined based on your resolution and zoom etc.). Just zoom out with your browser and it should list the full amount of options. Alternatively, click on the device using the device hostname hyperlink under the 'hostname' column on the far-left. That takes you to another screen where you can scroll to the bottom of the left-most column again and choose 'Troubleshooting' > 'Speed Test'.

The IOS-XE SDWAN image contains containerised iPerf3 client and server functionality meaning you can perform speed tests to internet-based iPerf3 servers or you can even perform speed tests between your sites. For example, you can perform a speed test between Branch-1 and DC. However, do note that the download speed could be limited on the upload speed of the remote server. For example, if Branch-1 has 1Gbps download, but DC has 250mbps upload, Branch-1 will only ever show a download speed of max 250mbps. The same situation applies for your upload speed being dependent on the download speed of the remote device, where of course download speed is not usually the bottleneck.

Please let me know if you've any further questions!

suppose bandwidth speed is different also region also different also show speed

The 'Up Speed' and 'Down Speed' should reflect the test results, i.e. what were the actual values measured in the data stream between the source and destination. The 'Up Bandwidth' and 'Down Bandwidth' should be the configured bandwidth values or expected values for the circuit. For example, the configured downstream bandwidth is 50Mbps (Down Bandwidth) but the actual speed test result was 43.33Mbps (Down Speed)

I'm not quite sure what you are asking with regard to 'region' sorry

PSuppose 1 router BW- 1GBPS is in Australia and one 1 on US - 800MBPS can the speed to show actual spped or it will be differ

Ignoring all the other issues concerning throughput "speed", if Australia is gig, up and down, and USA is 800 Mbps, up and down, Australia<>USA, at best, shouldn't exceed 800 Mbps.

BTW, for connections like an Australia<>USA performance issues can be as much, if not more so, due to distance based latency than bandwidth.

BTW, if a speed test doesn't come close to 800 Mbps, besides the numerous usual issues, as a LFN, it adds in its issues too.
