copy tftp flash os


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.

Parameters and options


For switches that have a separate out-of-band management port, the oobm parameter specifies that the TFTP traffic must come in through the out-of-band management 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 out-of-band management port.

Switch-to-switch, from either flash in source to either flash in destination

To download a software file from secondary flash in a switch with an IP address of to the secondary flash in a destination switch, you would execute the following command in the destination switch's CLI:

switch# copy tftp flash flash /os/secondary secondary
