So 10 port router, all have a separate subnet?
If so, what I said previous still stands.
Whatever vlan you use in the switch on any port that goes to a router port, that router port will use that vlan.
So Router Port 1 is connected to switchport 1 with it set to vlan 10. The network on router port 1 will use vlan 10 on any other switchport that is set to vlan 10. If you set switchports 1-6 to vlan 10, 2-6 are available to use for devices to connect to the subnet on router port 1. Same with router port 2 and 3 and 4 and ....
Whatever switchport you connect to a physical router interface determine the vlan it uses by the pvid of that switchport.
If you had a trunk port from router to switch, that's different.
You can set the switches management interface to whatever vlan you want. In your example, assign an IP for the switch in vlan 100 (or use dhcp) and it will use that vlan as management.
