Chapter 7 Switch Operating Procedures
Managing the Configuration Files
The following example shows what appears on the switch when the saveallcnf command is used without
the -v option:
pop20one.7.PXM.a > saveallcnf
The 'saveallcnf' command can be time-consuming. The shelf
must not provision new circuits while this command is running.
Do not run this command unless the shelf configuration is stable
or you risk corrupting the saved configuration file.
Do you want to proceed (Yes/No)? y
saveallcnf: shelf configuration saved in C:/CNF/pop20one_01_200006151550.zip.
Note Cisco Systems recommends that you use an FTP client to copy the saved configuration file to a
workstation. This ensures that you have a backup copy if the PXM45 Hard Drive card fails.
Subsequent usage of the saveallcnf command will overwrite an existing older configuration file,
if more than one file exists in the CNF directory.
Clearing a Configuration
There are two commands that allow you to clear the switch configuration: clrcnf and clrallcnf.
To clear switch provisioning data such as the PNNI controller, AXSM ports, and SPVC connections,
enter the clrcnf command. This command clears all configuration except the following data:
• IP address configuration
• Node name
• Software version data for each card
• SNMP community string, contact, and location
• Date, time, time zone, and GMT offset
To clear the entire configuration, enter the clrallcnf command. This command clears all the provisioning
data and most of the general switch configuration parameters, such as the switch name and SNMP
configuration. The clrallcnf command clears all IP addresses except the boot IP address.
Note When 4 or more RPM-PR cards are installed in the switch, a standby PXM45 can take approximately 45
minutes to reach standby state after the clrallcnf is entered.
Restoring a Saved Configuration
You can restore a configuration if all of the following statements are true:
• No save or restore process is currently running.
• No configuration changes are in progress.
• The switch is not hosting any critical calls.
