Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Where:
name—(Optional) specifies the name of the ATM PVC interface you create.
•
vpi—Specifies the ATM network virtual path identifier (VPI) of this PVC.
•
•
vci—Specifies the ATM network virtual channel identifier (VCI) of this PVC.
•
qsaal—(Optional) specifies theQ.2931 signaling ATM adaptation layer (QSAAL) encapsulation
type.
Note
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 15
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
Step 16
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-if)# umts-iub local ip-address port
For example, the following command configures the umts-iub local interface with an IP address and port
of 20.20.20.21 6666:
Router(config-if)# umts-iub local 20.20.20.21 6666
OL-15667-03
Typically AAL5 PVCs are defined using qsaal encapsulation. However, if the traffic profile is
such that the AAL5 packets exceed normal signaling (272 bytes) payload size, it is
recommended that the PVC be defined using AAL0.
This is commonly true for OAM PVCs and synchronization PVCs. NodeB Application Part
(NBAP) and Access Link Control Application Part (ALCAP) PVCs can be defined using qsaal
encapsulation.
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.
