It might read better if you replaced "to" here with "to/from".

This is a little nit-picky, but it might be worth removing "Number of"
here and replacing "add to" with "add to/remove from" so it is "VXLAN
ID to add to/remove from port filter list." just so that it reflects
that you can both add and remove using this method.

For this line I might be in favor of simplifying it down to something
like "ID of the port to modify VXLAN filter of." That way it doesn't
need all the slashes to account for both adding and removing.
