Chapter 4 Configuring the Cisco 3825 Mobile Wireless Edge Router in a RAN-O Solution with the Command-Line
Configuration Sequence
Step 17
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-if)# umts-iub remote ip-address port
For example, the following command configures the umts-iub remote interface with an IP address and
port of 20.20.20.20 6666:
Router(config-if)# umts-iub local 20.20.20.20 6666
Step 18
Exit the interface configuration mode.
Router(config-if)# exit
Router(config)#
Step 19
Specify the ATM/IMA interface that the PVCs will be assigned to and enter the sub-interface mode.
Router(config)# interface ATM
slot/IMA<group-number>[.<subinterface-number> {multipoint
point-to-point}]
Where:
•
slot—Specifies the slot location of the ATM IMA port adapter.
•
group-number—Specifies the group number of the IMA group.
•
subinterface-number—Specifies the sub-interface number.
For example, the following command specifies the slot number as 0 and the group number as 0.1 for
multipoint:
Router(config)# interface ATM0/IMA0.1 multipoint
Step 20
Create an ATM path on the UMTS Iub interface, enter the following command:
Router(config-subif)# atm umts-iub
Step 21
Create an ATM PVC:
Router(config-subif)# pvc [
name] vpi/vci [qsaal]
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
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.
