Transferring Software Files to and from the Switch
This section describes how to copy software files between the switch and another computer when the
switch is in backup boot mode. In most cases, you will use this procedure because the switch cannot
completely load the runtime software and ends start up in either backup boot mode or shell mode.
Note When the switch displays the switch prompt (which includes the switch name), copy files to the switch
using the procedure described in the “Copying Software Files to the Switch” section in Appendix A,
“Downloading and Installing Software Upgrades.”
The Cisco MGX 8850 and the Cisco MGX 8950 switches provide a File Transfer Protocol (FTP) service
to support file transfers between the switch and other computers. If you have FTP client software and
network connectivity to both the switch and the server where the software files are stored, you can FTP
files directly from the server to the switch. You can also use this FTP service to recover log files, boot
and runtime files, or saved configuration files before replacing the hard disk.
To transfer files with the FTP service, use the following procedure.
pwd Display the present working directory.
When you first start a session in backup boot mode, the present working directory is a
directory on a remote server as specified by the runtime software bootchange
command. To change to a directory on the C: drive, enter the cd command.
Syntax: pwd
Example: pwd
rename Renames a file.
Syntax: rename “<old file name>”, “<new file name>”
Example: rename “test”, “deleteme”
whoami Lists the login name for the current session.
Since there is no user log-in procedure for backup boot mode, the username reported by
the whoami command is the username configured by the runtime software bootchange
command for remote server access.
Syntax: whoami
Example: whoami
