Subinterfaces on EHWIC-4ESG ports

Question:

I am trying to configure Cisco 3560 Price subinterfaces on EHWIC-4ESG ports but although it is showing that I can put in when I type in the ? it is saying invalid input entry when I put in the command. is there any way, I can create subinterfaces on these ports or is the only option to create VLANs with the IPaddresses and create the port as a trunk port? Any advice response will be much appreciated.

Answer:

Configuring several vlans, assigning switch ports to a vlan, and configuring interface vlan for each vlan would be the usual answer for accomplishing this. And sounds like that Cisco Catalyst 3560 is what you have done.
