Hi,
From interface configuration mode, you can enter subinterface configuration mode. Subinterface configuration mode is a submode of interface configuration mode. In subinterface configuration mode you can configure multiple virtual interfaces (called subinterfaces) on a single physical interface.
In the following example, a subinterface is configured for serial line 2, which is configured for Frame Relay encapsulation. The subinterface is identified as "2.1" to indicate that it is subinterface 1 of serial interface 2. The new prompt hostname(config-subif)# indicates subinterface configuration mode. The subinterface can be configured to support one or more Frame Relay PVCs.
Router(config)# interface serial 2
Router(config-if)# encapsulation frame-relay
Router(config-if)# interface serial 2.1
Router(config-subif)#
To exit subinterface configuration mode and return to interface configuration mode, use the exit command. To end your configuration session and return to privileged EXEC mode, press Ctrl-Z or enter the end command.
Hope to help !!

Hello,
There are various documents explaining the sub-interfaces configuration depending upon the network scenario. Here are few links:
Using subinterfaces on an Ethernet port for intervlan routing:
https://www.cisco.com/en/US/docs/security/asa/asa81/config/guide/intrface.pdf
Frame-relay subinterfaces:
http://www.cisco.com/warp/public/125/16.pdf
Hope this helps.
Regards,

Please read Router on Stick concept from the Cisco documentation.
It will provide you the effective idea to create subinterface of any interface.
