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 1and a VCI of 200:
Router(config-subif)# pvc 1/200
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 22 Configure the AAL and encapsulation type to AAL0 encapsulation.
Router(config-if-atm)# 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-atm)# encapsulation aal0
Step 23 Exit the interface atm configuration mode.
Router(config-if-atm)# exit
Step 24 To configure the local parameters required to establish an IP/UDP backhaul connection, enter the
following command including the IP address and port you want to establish the IP/UDP backhaul
connection from.
Router(config-subif)# umts-iub local ip-address port
For example, the following command configures the umts-iub local interface with an IP address of
192.168.10.2 and a port of 6000:
Router(config-subif)# umts-iub local 192.168.10.2 6000
Step 25 To configure the remote parameters required to establish an IP/UDP backhaul connection, enter the
following command including the IP address and port you want to establish the IP/UDP backhaul
connection from.
Router(config-subif)# umts-iub remote ip-address port
For example, the following command configures the umts-iub remote interface with an IP address of
192.168.10.1 and a port of 6000:
Router(config-subif)# umts-iub remote 192.168.10.1
Note In the above procedure, traffic for PVC 1/200 will be off-loaded to the alternate backhaul (192.168.10.2
— 192.168.10.1).
