This post is about a VCN3000 server network card bond issue. Please find the solution as you read further down.
【Problem description】
The customer said that the server network card did two bindings, but only one binding worked.
Product type: VCN3010.
【Problem analysis】

We checked the customer's question - it’s just the server mechanism.
When we logged in to the OMU portal, we could bond all the network cards as two bonds.
However, only one bond for business and the other bond for the VMU two-node cluster heartbeat bond.
So this only one bond is working.
【Root cause】
Server mechanism issues.
