Switch Operating Procedures

This chapter describes procedures you can use to manage the Cisco MGX 8850 and Cisco MGX 8950

switches.

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.

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. The file is named using the switch name and the current date as follows:

Name_01_DateTime.zip.

The date appears in YYYYMMDD (year, month, day) format, and the time appears in HHMM (hour,

minute) format. For example, if the configuration for a switch named mgx8850a were saved on February

29th, 2000 at 2:31pm, the file would be named C:/CNF/mgx8850a_01_200002291431.zip.

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

configuration exactly as it was when the configuration file was saved. If the boot and runtime files have

been removed from the switch, they must be transferred to the switch before the restored configuration

can start.

Note If you have upgraded software on the switch since the last time the configuration was saved, a

configuration restore will restore the non-upgraded software versions and configuration data. The

software does not allow you to save a configuration and restore it on a different revision level of the

software.
