First we will examine how we will do this in the router (how we are going to split the ports between vlans)

VLAN2 will use : PORTS 9 to 16 and 18 and 20
VLAN1 will keep: PORTS 1 to 8 and 17 and 19

You can set this as you wish but by default this is how we will configure the VLANs.
Whatever ports you exclude from VLAN2 will by default STAY assigned to VLAN1
You will need to repeat this procedure for both VLANS, we will show how to add ports to
VLAN2 the same will have to be done for VLAN1, you should first do this for VLAN2,
save the configurated VLAN2 settings to running config, so they will be applyed then
go configure the ports for VLAN1.
