You can use the display interface command,  If the interface is a Layer 3 interface, Route Port is displayed.

 

display interface

display interface2

 

Another simple method: If an interface can be configured with an IP address, it is a Layer 3 interface.

The portswitch command changes the working mode of Ethernet interfaces from Layer 3 mode to Layer 2 mode.
The undo portswitch command changes the working mode of Ethernet interfaces from Layer 2 mode to Layer 3 mode.

But In the S series switches, only S5720HI, S5720EI, S6720S-EI,S6720EI  and s73/77/93/97  support switching between Layer 2 and Layer 3 modes.

In ENSP,  you can use CE6800/CE12800 instead of S37/S57, both of them support layer 3.
