Configuring ATM on the Cisco 3660

Step 1

Router(config)# interface atm <slot>/ima<grp#>

[subinterface-number [multipoint |

point-to-point

]]

Enters interface configuration mode to configure ATM
interface 0/0 or an ATM subinterface.

Note

To configure an IMA group on each ATM
interface, enter the IMA group and group
number.

The default for subinterfaces is multipoint.

For all Scenarios: Set up three subinterfaces for
point-to-point.

Step 2

Router(config-if)# pvc [name] vpi/vci

Creates an ATM PVC for voice traffic and enters ATM
virtual circuit configuration mode.

Note

AAL2 encap is not supported for ilmi and
qsaal PVCs.

Step 3

Router(config-if-atm-vc)# encapsulation aal2

Sets the encapsulation of the PVC to support AAL2
voice traffic. This automatically creates channel
identifiers (CIDs) 1 through 255.
