I have a stack of N3048 as core switches, with some vlans running across.

I have connected a monitoring appliance to a port (gi3/0/46), and i need to monitor all these VLANs traffic.

I have created a new vlan (200) for remote-span
I have set the port to trunk mode, and allowed VLAN 200
I add my first vlan to be mirrored:

monitor session 1 source vlan 50 rx

I set the destination port

monitor session 1 destination remote vlan 200 reflector-port gi3/0/46

At this point i am not able to add any other vlan, the error is  Configuration data could not be added.

What should i do?

Thank you!
