Chapter20 Configuring Frame Relay to ATM Interworking Port Adapter Interfaces
Configuring Frame Relay to ATM Interworking Functions
Note You must shut down the interface prior to Frame Relay encapsulation.
Example
Switch(config)# interface serial 0/1/0:5
Switch(config-if)# shutdown
Switch(config-if)# encapsulation frame-relay ietf
Switch(config-if)# no shutdown
Displaying Frame Relay Encapsulation
To display Frame Relay encapsulation, use the following user EXEC command:
Example:
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:

Configuring Frame Relay Serial Interface Type
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:
Example
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
Command Purpose
show interfaces serial card/subcard/port:cgn Displays Frame Relay encapsulation.
Command Purpose
Step 1
Switch(config)# interface serial
card/subcard/port:cgn
Switch(config-if)#
Selects the interface to be configured.
Step 2
Switch(config-if)# frame-relay intf-type {dce |
nni}
Selects a Frame Relay interface type.
