Configuring ATM AAL5 SDU Support over MPLS
ATM AAL5 SDU support over MPLS encapsulates ATM AAL5 service data units (SDUs) in MPLS
packets and forwards them across the MPLS network. Each ATM AAL5 SDU is transported as one
packet.
To configure ATM AAL5 SDU support over MPLS, enter the following commands beginning in global
configuration mode:

Verifying ATM AAL5 SDU Support over MPLS
To verify that ATM AAL5 SDU support over MPLS is configured on a PVC, issue the show mpls
l2transport vc command.

Configuring ATM-to-ATM PVC Local Switching
The following ATM line cards are supported for Cisco 10000 series routers:
•
4-port OC-3/STM-1
•
8-port E3/DS3
Command
Purpose
Step 1
Router(config)# interface type slot/port
Specifies the interface by type, slot, and port number, and enters
interface configuration mode.
Step 2
Router(config-if)# pvc [name] vpi/vci
l2transport
Creates or assigns a name to an ATM PVC.
The l2transport keyword indicates that the PVC is a switched
PVC instead of a terminated PVC. Enters L2transport VC
configuration mode.
Step 3
Router(config-if-atm-l2trans-pvc)#
encapsulation aal5
Specifies ATM AAL5 encapsulation for the PVC.
Make sure you specify the same encapsulation type on the PE
and CE routers.
Step 4
Router(config-if-atm-l2trans-pvc)# xconnect
peer-router-id vcid encapsulation mpls
Binds the attachment circuit to a pseudowire VC.
