Hi there,

I have virtualized my CNA WWNs to



and it looks like there is no Fabric Login possible anymore.

The Nexus 5020 keeps suspending the VFC because of too many invalid FLOGIs.

Does anyone have an idea why?

The response to the FLOGI I see with Wireshark is an LS_RJT (LinkService Reject) but

unfortunately it only contains an unknown reason code. So no help from this side.

Is there anything special about the used WWNs? Because if I use these WWNs on a FC HBA in conjunction wioth a Brocade Fabric

it works perfect. Any hint is highly welcome.
