Chapter20 Configuring Frame Relay to ATM Interworking Port Adapter Interfaces
Configuring Frame Relay to ATM Virtual Connections
To configure a Frame Relay to ATM service interworking PVC, perform the following steps beginning
in global configuration mode:
Note Since release 12.0(1a)W5(5b) of the ATM switch software, addressing the interface on the route
processor has changed. The ATM interface is now called atm0, and the Ethernet interface is now called
ethernet0. Old formats (atm 2/0/0 and ethernet 2/0/0) are still supported.
Note The row index for rx-cttr and tx-cttr must be configured before using this optional parameter. See
Chapter 9, “Configuring Resource Management.”
Examples
The following example shows how to configure the internal cross-connect PVC on Switch B between
serial interface 0/1/0:5, DLCI = 43, and ATM interface 3/0/2, VPI = 2, VCI = 100 (with the translation
option):
Switch-B(config)# interface serial 0/1/0:5
Switch-B(config-if)# frame-relay pvc 43 service translation interface atm 3/0/2 2 100
The following example shows how to configure the internal cross-connect PVC on Switch C between
ATM interface 4/1/0, VPI = 2, VCI = 100 and ATM interface 0/0/1, VPI 50, VCI = 255:
Switch-C(config)# interface atm 4/1/0
Switch-C(config-if)# atm pvc 2 100 interface atm 0/0/1 50 255
Each subsequent VC cross connection and link must be configured until the VC is terminated to create
the entire PVC.
Note The Frame Relay to ATM service interworking PVC must be configured from the serial interface and
then cross-connected to the ATM interface.
Command Purpose
Step 1
Switch(config)# interface serial
