+vxlan vxlan123 {
+    remote 192.168.188.2
+    vni 123

[edit]
[email protected]# commit
[ interfaces vxlan vxlan123 ]
vxlan: destination port not specified
Will use Linux kernel default (non-standard value)
Use 'dstport 4789' to get the IANA assigned value
Use 'dstport 0' to get default and quiet this message

[email protected]# set interfaces vxlan vxlan123 remote-port 4789
[edit]
[email protected]# commit
[ interfaces vxlan vxlan123 remote-port 4789 ]
Changing remote port requires delete/create this vxlan interface

[[interfaces vxlan vxlan123]] failed

maybe it is better to don't commit the change when the remote-port is not set?

We should not emit any warning at all - this was caused by a bug in the remote-port implementation.

@rob Fix will be in next rolling release

the commit success now in the latest rolling.

but now 8472/UDP is used. Who set this? The Kernel?
according to https://tools.ietf.org/html/rfc7348 the port 4789 should use.

8472 is the default port used by the Kernel, and thus fully backwards compatible with older installations. 4789 is the IANA assigned value which you could configure using remote-port.

This behavior could be changed but I see no reason to do so as the port can be adjusted via CLI.
