You must shut down the interface prior to Frame Relay encapsulation. 

Switch(config)# interface serial 0/1/0:5

Switch(config-if)# shutdown

Switch(config-if)# encapsulation frame-relay ietf

Switch(config-if)# no shutdown

To display Frame Relay encapsulation, use the following user EXEC command:

The following example displays the Frame Relay encapsulation configuration on serial interface 0/1/0:5:

Switch# show interfaces serial 0/1/0:5

Serial0/1/0:5 is up, line protocol is up

  Hardware is FRPAM-SERIAL

  MTU 4096 bytes, BW 320 Kbit, DLY 0 usec, rely 0/255, load 1/255

Encapsulation FRAME-RELAY IETF, loopback not set, keepalive not set

  Last input never, output never, output hang never

  Last clearing of "show interface" counters never

  Input queue: 0/75/0 (size/max/drops); Total output drops:

To configure an interface as a data communications equipment (DCE) or Network-Network Interface 
(NNI) type, perform the following steps, beginning in global configuration mode:

The following example shows how to configure Frame Relay interface type NNI for serial 
interface 0/1/0:5:

Switch(config)# interface serial 0/1/0:5

Switch(config-if)# frame-relay intf-type nni

show interfaces serial card/subcard/port:cgn Displays Frame Relay encapsulation.

Switch(config)# interface serial 
card/subcard/port:cgn

Switch(config-if)# 

Selects the interface to be configured.

Switch(config-if)# frame-relay intf-type {dce | 
nni}

Selects a Frame Relay interface type.
