Cisco ATM Services (AXSM) Configuration Guide and Command Reference for MGX Switches
Release 5.2, Part Number OL-6484-01 Rev. C0, September 2005
Chapter 3 Provisioning ATM Services
General AXSM Configuration Procedures
The default ILMI prefix matches the PNNI node prefix and the SPVC prefix, both of which are described
in the Cisco PNNI Network Planning Guide for MGX and SES Products. If you change the:
• PNNI node prefix, the SPVC prefix and the ILMI prefix remain unchanged.
• SPVC prefix, the ILMI prefix will change with it, as long as no ILMI prefix is assigned directly to
the port.
To eliminate the possibility of having a future SPVC prefix change affect dynamic addressing on a port,
assign one or more ILMI prefixes to the port.
The following procedure describes how to enable or disable dynamic addressing and how to assign an
ILMI address prefix to a port.
Note The Cisco MGX 8850 (PXM45) and Cisco MGX 8950 support up to 255 ILMI prefixes per AXSM card,
and these prefixes can be assigned to one port or distributed among the ports.
Step 1 Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 2 To display the dynamic addressing status of a port, use the dsppnport command. For example:
M8950_DC.7.PXM.a > dsppnport 5:1.1:11
Port: 5:1.1:11 Logical ID: 17111051
IF status: up Admin Status: up

The Addrs-reg field shows whether the dynamic addressing feature is enabled or disabled.
Step 3 To view the ILMI prefixes assigned to a port, enter the dspprfx command as follows:
MGX8850.7.PXM.a > dspprfx <
portid
>
Replace portid with the port address using the format slot:bay.line:ifnum. For example:
MGX8850.7.PXM.a > dspprfx 5:1.1:11
