  • 1.  How to change VXLAN port in NSX manager?

    Posted Jun 19, 2016 02:26 PM

    Hi Expert,

    I'm using NSX manager 6.2.2 and its default VXLAN UDP port is 8474.

    I want to change it to IANA default UDP port 4789.

    How can I do that?

    Thanks very much,

    Mike

    Hi Mike,

    That one is easy; upgrade to 6.2.3, which uses 4789 by default and you have the ability to change the port as well (from the logical network preparation).

    Also, should you not want to upgrade for some reason you should be able to change it via the API call documented in this blog here
