# How to identify what is specifing UDP port for VXLAN?

Hello -

With RHEL 7.1 the hardware vendor I work for offered VXLAN offload support in their ethernet driver / hardware (be2net).

I'm attempting to configure them, and I'm running into an issue.

The issue would be that my driver requires that we use a single UDP port for VXLAN, and can only identify one.

However I'm getting the following output when I attempt to enable VXLAN and I'm trying to figure out how to specify that only one UDP port be used (if possible)

The errors I'm getting:

[15509.491042] be2net 0000:02:00.0: Enabled VxLAN offloads for UDP port 6677
[15509.503333] be2net 0000:02:00.1: Enabled VxLAN offloads for UDP port 6677
