General PXM1E 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. If you change the 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.
The Cisco MGX switches support up to 255 ILMI prefixes per PXM1E card, and these prefixes can be
Note
assigned to one port or distributed among the ports.
Establish a configuration session using a user name with GROUP1 privileges or higher.
Step 1
Step 2 To display the dynamic addressing status of a port, use the dsppnport command. For example:
mgx8830a.1.PXM.a > dsppnport 1:2.3:1

The Addr-reg field shows whether the dynamic addressing feature is enabled or disabled.
To view the ILMI prefixes assigned to a port, enter the dspprfx command as follows:
Step 3
mgx8830a.1.PXM.a > dspprfx <portid>
Replace portid with the port address using the format slot:bay.line:ifnum. These parameters are
described in
mgx8830a.1.PXM.a >
INFO:
In the example above, no ILMI prefixes have been assigned to the port, so the port will use the prefix
configured for the SPVC prefix.
If you want to change the dynamic addressing configuration, bring down the port to be configured with
Step 4
the dnpnport command. For example:
mgx8830a.1.PXM.a > dnpnport 1:2.3:1
