Hi Guys,
I have a problem when I configure port as an access port.
First , this is my network

When I configure any port to any VLAN it dose not work !!
But when I'm not change these port (all port stay in native VLAN or VLAN 1)it work !
And When I replce the switch to 3650 as shown below

All think change !
When I don't assign any port to VLAN , its not work and vice versa !
I really dont understand whats happen !!
Please advise,
