Chapter 3 Provisioning ATM Services
General AXSM Configuration Procedures
General AXSM Configuration Procedures
This section describes the following general procedures for configuring AXSM card communications:
• Adding ATM Ports
• Configuring Inverse Multiplexing over ATM
• Partitioning Port Resources between Controllers
• Selecting the Port Signaling Protocol
• Assigning Static ATM Addresses to Destination Ports
• Configuring ILMI on a Port
• Configuring AXSM Line Clock Sources
• Configuring PNNI Links
• Configuring SPVCs and SPVPs
• Defining a Feeder Port
• Defining Destination Addresses for Static Links
• Configuring Point-to-Multipoint SPVCs and SPVPs
The procedures in this section use AXSM commands and show the syntax for AXSM commands. See
Chapter 5, “AXSM Command Reference,” for descriptions of the AXSM commands and parameters.
See the Table 1-3 on page 1-4 for a list of the AXSM model numbers, back cards, and the number of
possible connections.
Some of the procedures in this section use PXM commands and PNNI commands. Refer to the Cisco
MGX 8800/8900 Series Command Reference, Release 5.2 for descriptions of the PXM and PNNI
commands and parameters.
For more information on port signaling, refer to the Cisco MGX 8800/8900 Series Configuration Guide,
Release 5.2.
For more information on ATM address planning, refer to the Cisco PNNI Network Planning Guide for
MGX and SES Products.
Adding ATM Ports
On an AXSM card, a logical port is also called a virtual interface and is represented by the ifNum variable.
The AXSM cards can have the follow ing types of interfaces:
• UNI (User-to-Network Interface) – Used for lines that connect to PBXs, ATM routers, and other
ATM devices that connect to the core ATM network through the switch. Only one logical UNI port
per line can be configured.
• NNI (Network-to-Network Interface) – Used for trunks that connect to other core ATM network
devices, such as another Cisco MGX switch. Only one logical NNI port per line can be configured.
• VNNI (Virtual Network-to-Network Interface) – Supports virtual trunk connections between two
ATM end stations. Multiple VNNI ports per line can be configured.
• VUNI (Virtual User-to-Network Interface) – You can configure multiple ports per line.
• EVUNI (Enhanced Virtual User-to-Network Interface) – You can specify a range of VPIs for one
interface, and this range of VPIs represents the virtual UNI trunk.
