Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
For example, the following command specifies the ATM PVC interface with a VPI of 2and a VCI of 1:
Router(config-if)# pvc 2/1
Note
Configure the AAL and encapsulation type to AAL0 encapsulation.
Step 14
Router(config-if)# encapsulation aal-encap
Where aal-encap specifies the AAL and encapsulation type.
For example, the following command specifies the AAL as AAL0:
Router(config-if)# encapsulation aal0
To set the UMTS Congestion priority for protected, enter the following command.
Step 15
Router(config-if-atm-vc)# umts-iub congestion priority protected
To set the UMTS Congestion priority to level 4, enter the following command.
Step 16
Router(config-if-atm-vc)# umts-iub congestion priority 4
To enable the UMTS Congestion Control under UMTS shorthaul interface, enter the following
Step 17
command.
Router(config-if)# umts-iub congestion-control
To set the DSCP value used as the interface default DSCP value to tag the backhaul packet, use the
Step 18
following command:
Router(config-if)# umts-iub set dscp value
Where value is a number chosen to represent that packet of traffic.
For example, the following command specifies the number 8 for the packet of traffic for the umts-iub
interface:
Router(config-if)# umts-iub set dscp 8
To overwrite the previous PVC 2/1 with a umts-iub interface DSCP of 16, use the following command:
Step 19
Router(config-if)# umts-iub set peering dscp value
Where value is a number chosen to represent that packet of traffic.

PVC definitions should match those on the NodeB and use the following definitions:
NBAP signaling–use qsaal
ALCAP signaling–use qsaal
AAL2 bearer–use encapsulation aal0
All other PVCs should use encapsulation aal0
Class of service should be defined to match the NodeB PVC class of service definitions. For
instance, if the NodeB has defined a PVC with CBR, the PVC on the Cisco 3825 router should
use the same CBR definitions.
OAM can be defined on the PVCs as well. If the NodeB has OAM enabled on its PVC, OAM
should be defined on the PVCs of the Cisco 3825 router as well.
