Cisco Systems 3825 Specify the ATM bandwidth as dynamic, Routerconfig-if#atm bandwidth dynamic

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

Configuration Sequence

Step 8 Specify the slot location and port of IMA interface group.

Router(config-if)# interface ATMslot/IMA<group-number>

Where:

•slot—Specifies the slot location of the ATM IMA port adapter.

•group-number—Specifies the group number of the IMA group.

For example, the following command specifies the slot number as 0 and the group number as 0:

Router(config-if)# interface ATM0/IMA0

Note Should you desire, the optional ima group-idcommand can be used to explicitly configure the IMA Group ID for the IMA interface. You cannot configure the same IMA Group ID on two different IMA interfaces; therefore, if you configure an IMA Group ID with the system-selected default ID already configured on an IMA interface, the system toggles the IMA interface to make the user-configured IMA Group ID the effective IMA Group ID. At the same, the system toggles the original IMA interface to select a different IMA Group ID.

Step 9 Disable the IP address configuration for the physical layer interface.

Router(config-if)# no ip address

Step 10 Specify the ATM bandwidth as dynamic.

Router(config-if)#atm bandwidth dynamic

Step 11 Create an ATM path on the UMTS Iub interface, enter the following command:

Router(config-if)# atm umts-iub

Step 12 Disable the ILMI keepalive parameters.

Router(config-if)#no atm ilmi-keepalive

Step 13 Create an ATM PVC:

Router(config-if)# 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—See Note.

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.
