Switch Operating Procedures
This chapter describes procedures you can use to manage the Cisco MGX 8830,
Cisco MGX 8850 (PXM1E/PXM45), and Cisco MGX 8950 switches and the Cisco 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.
To prevent overwriting of older configuration files, transfer those files to another storage media.
Tip
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.
