Crazy about VMware SD-WAN

 In this Blog we look into the necessary settings for allowing Secure Access to the EDGE via CLI. This new feature allows priviledged secure access using script and shell and for Basic access there is a scripted procedure with a restricted set of commands. In principle many of the information can also be retrieved using remote diagnostics BUT the CLI access is much quicker without waiting for the next hearbeat (~ 30 seconds) before getting the result. These are the necessary steps to activate the new feature using key-based access Step 1: Activating Secure Edge Access (once per customer) Step 2: In the same window switch to Key Based Authentication Step 3: any superuser can then define if Basic (script based only) or Priviledged (script or shell) should be allowed NOTE: the CLI username is   <1 character e ... enterprise, o...operator><user-id><username (with "@" and "." converted to "_")> Now the user can under "My Account"/...

Around 2 months ago when doing a Speedtest check of my links I experienced a substancial reduction of measured UPlink and DOWNlink speed. As I only have a single link to the Internet using Cable Modem connectivity which is a shared linktype, after some retries I assumed the problem to be at the Service Provider and some congestion there. I contacted the Service Provider but he assured me, that this is not the case. Then I found the real "culprit". It was my VMware SD WAN Edge which drastically reduced the bandwidth sent out via the Overlay. When checking the Edge I found out that the last measured Bandwidth was around 40/10 instead of 180/40 Mbps.   I was quite unsure about that measured  bandwidth and found out that according to this VMware knowledge base article ... ... on wired links the bandwidth test is only done when there is a Link Up event or after 7 days . So what seemed have happened was, that the last bandwidth measurement took place at a time, where due to s...
