Cisco Systems 3825 manual Routerconfig-if-atm-vc#umts-iub congestion priority

Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line

Configuration Sequence

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 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.

Step 14 Configure the AAL and encapsulation type to AAL0 encapsulation.

Router(config-if)# encapsulation aal-encap

Where aal-encapspecifies the AAL and encapsulation type.

For example, the following command specifies the AAL as AAL0:

Router(config-if)# encapsulation aal0

Step 15 To set the UMTS Congestion priority for protected, enter the following command.

Router(config-if-atm-vc)#umts-iub congestion priority protected

Step 16 To set the UMTS Congestion priority to level 4, enter the following command.

Router(config-if-atm-vc)#umts-iub congestion priority 4

Step 17 To enable the UMTS Congestion Control under UMTS shorthaul interface, enter the following command.

Router(config-if)#umts-iub congestion-control

Step 18 To set the DSCP value used as the interface default DSCP value to tag the backhaul packet, use the 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

Step 19 To overwrite the previous PVC 2/1 with a umts-iub interface DSCP of 16, use the following command:

Router(config-if)#umts-iub set peering dscp value

Where value is a number chosen to represent that packet of traffic.
