3.11.2.13 Configuring ATM Interface Parameters
ATM interface parameters can be configured for SONET/SDH ports in access mode,
TDM ports or channels supporting ATM encapsulation, and IMA multilink bundles.
The parameters allow users to configure characteristics of an ATM interface. The
7705 SAR-8 and 7705 SAR-18 support configuration of the following ATM interface
parameters:
• cell-format — allows the user to select the ATM cell format to be used on a given
interface: UNI or NNI (NNI is not supported on SONET/SDH interfaces)
• min-vp-vpi — allows the user to set the minimum allowable virtual path identifier
(VPI) value that can be used on the ATM interface for a VPC
• mapping — allows the user to configure ATM cell mapping for DS3 clear
channels. Since E3 ports only support G.751 framing with direct cell mapping,
ATM mapping is hard-coded for direct mapping for an E3 port (you will get an
error message if you try to change the value).
