Management and Configuration Guide K/KA/KB.15.15

Boots from the flash image and startup-config file. A switch covered in this guide
(with multiple configuration files), also uses the current startup-config file.
3. To confirm that the software downloaded correctly, execute show system and check the
Firmware revision line.
Switch-to-switch download
You can use TFTP to transfer a software image between two switches of the same series. The CLI
enables all combinations of flash location options. The menu interface enables you to transfer
primary-to-primary or secondary-to-primary.
Downloading the OS from another switch
Where two switches in your network belong to the same series, you can download a software
image between them by initiating a copy tftp command from the destination switch. The options
for this CLI feature include:
• Copy from primary flash in the source to either primary or secondary in the destination.
• Copy from either primary or secondary flash in the source to either primary or secondary flash
in the destination.
Downloading from primary only
Syntax
copy tftp flash ip-addr flash [ primary | secondary ] [oobm]
When executed in the destination switch, downloads the software flash in the source switch's
primary flash to either the primary or secondary flash in the destination switch.
For switches that have a separate OOBM port, the oobm parameter specifies that the TFTP traffic
must come in through the OOBM interface. If this parameter is not specified, the TFTP traffic comes
in through the data interface. The oobm parameter is not available on switches that do not have
a separate OOBM port.
If you do not specify either a primary or secondary flash location for the destination, the download
automatically goes to primary flash.
Example
To download a software file from primary flash in a switch with an IP address of 10.29.227.103
to the primary flash in the destination switch, you would execute the following command in the
destination switch's CLI:
Figure 126 Switch-to-switch, from primary in source to either flash in destination
Downloading from source flash
Syntax
copy tftp flash ip-addr /os/primary | /os/secondary [ primary |
secondary ] [oobm]
This command (executed in the destination switch) gives you the most options for downloading
between switches. If you do not specify either a primary or secondary flash location for the
destination, the download automatically goes to primary flash.
