To create a vlan with tag "100", it's one line:
vlan 100
To add an interface to that vlan, it's two lines. Go to your specific interface, then assign the vlan:
interface g1/0/10
switch access vlan 100
So let's say you have a 48-port switch and want to create two vlans, 100 and 200, and put half of the interfaces in each vlan. Here are your commands:
config t
vlan 100
vlan 200
interface range g1/0/1 - 24
switchport access vlan 100
no shut <------ you may not need this line
interface range g1/0/25 - 48
switchport access vlan 200
no shut <------ you may not need this line
end
write memory
So if you don't count the config and end and save commands, it's 6 lines. The "no shut" command may be needed if the ports were shutdown. Plug your Blie Iris server into both VLANs (like port 24 (vlan 100) and port 25 (vlan 200) ). Your router would connect to one VLAN only.
Think of this configuration as having two separate 24-port switches.
