ICX 7150 Switch question

[BusinessUser]

Is this just a layer 2 switch?

Can it support router functions like NAT and layer 3 ip interface?

How do I create a vlan when I cannot key in int vlan 1?

What are the differences between I, C and X port?

I know that c is copper, x is fiber. How about i ?

What are the differences in terms of configuration you can apply to these different types of port?

Apologies for the delay in getting back on this. 

Did check regarding this , Its more of a naming convention used for the product family. and the features it brings. as a stackable switches that provide chassis-level performance, bringing scalability to the deployment.
