Switch Operating Procedures

This chapter describes procedures you can use to manage the MGX 8850 (PXM1E/PXM45), MGX

8850/B, MGX 8950, MGX 8830, MGX 8830/B switches and the MGX 8880 Media Gateway.

Managing the Configuration Files

The following sections describe how to save a switch configuration in a single zipped file, clear or erase

a configuration, and restore a configuration from a file.

Saving a Configuration

After configuring your switch or after making configuration updates, it is wise to save the configuration.

It is also good practice to save the configuration before upgrading the software. Restoring a saved

configuration is much easier than re-entering all the commands used to configure the switch.

To save a configuration, enter the saveallcnf command, which saves the configuration to a file in the

C:/CNF directory. To prevent the saved files from consuming excessive disk space, the switch preserves

only two configuration files. If you save a third time, the older of the two existing files is replaced by the

newer file.

Tip To prevent overwriting of older configuration files, transfer those files to another storage media.

A saved configuration file is named using the switch name and the current date as follows:

switchname_dateCode<N|O>

The date appears in YYMMDD (year, month, day) format. When two configurations are saved on the

same day, the letters N or O indicate if the saved file is the newest or oldest configuration file. For

example, if the configuration for a switch named M8950_SF is saved on January 24th, the file is named

C:/CNF/M8950_SF_040124N. An older file that was saved on the same day would be renamed

M8950_SF_040124O. If the configuration is saved on different days, both files are saved with the N

indicator.

When you save a configuration, the switch saves all configuration data, including the software revision

levels used by the cards in the switch. The saved configuration file does not include the boot and runtime

software files. Should you need to restore a configuration, the restoreallcnf command restores the
