That sounds like the configuration may be off, or we're not considering the back-end settings somewhere in this configuration. If you want to send me the configuration I'd be happy to take a look, but I see your account has purchased support and a technical support case with a dedicated technician taking a look with you would go faster.

Yep, when i change port speed or changing a port from access to trunk and adding vlan I lost access to all devices plugged in that switch.

Same problem on N2048p and N1108p.

Are you changing port configuration with the update or adding/removing any VLANs to the network?
