Steps
1
Check the contents of the switch configuration file.
1. Open the telnet connection using the following command:
ZW6T:SWU,<index>;
2. Check the contents of the switch configuration file:
ESB26#show running-config
3. Input 'exit' to close telnet connection. It will prompt:
'DO YOU WANT TO DOWNLOAD CONFIGURATION FILE FROM LAN SWITCH?'
Select 'Y' to download the file directly, or 'N' to manually download as described in the following step.
2
Back up the configuration file. (YFM)
1. Download the configuration file from LAN switch to the system with the YFM command.
ZYFM:DCF:SWU,<index>;
2. Check the system configuration file with the W6R command.
ZW6R:SWU,<index>;
3
Check the contents of your script file system.
For instructions, see File System for Configuration Script Files in ESB User Guide.
Note: For ESB24-D, see Script Configuration File in User Manual ESB24-D.
4
Back up the script files to a TFTP server outside the network element.
For instructions, see File System for Configuration Script Files in ESB User Guide.
5
Remove the sensitive information from the script file system.
For instructions, see File System for Configuration Script Files in ESB User Guide.
6
Clear the configuration by rebooting the switch to factory defaults.
Tip: Rebooting the switch to factory defaults means that the VLAN and STP/MSTP configurations will also be initialized. To avoid possible L2
loops, it is highly recommended that you cut possible cabling loops between switch and site L2/L3 multi-layer switches. Redundant backup links
should be administratively disabled from the site on which L2/L3 device(s) are connected to the ESB that will be rebooted to factory defaults.
For ESB26:
ESB26#reload to-defaults
ESB26#copy running-config startup-config
For ESB24-D:
ESB24-D#restore factory-defaults
ESB24-D#restore factory-startup
ESB24-D#reload
