Copy NX-OS over to Nexus 7K bootflash from console port

I need to copy a newer NX-OS over to a Nexus 7K device from the console port, I tried tftp from a system on the network and it timedout so by using the console port it should be much faster. This needs to be done with out any interruption in service and can be done that way.

I’m wanting  a recommendation on the best way to copy over the NX-OS over to the Nexus bootflash. There is plenty of space for the NX-OS on the bootflash for the NX-OS. I can use TFTP, or Secure CRT. I would like a step by step process for this?


Thank you,

I've never tried (nor considered) to copy OS files over the console port.  The size of the file would make it take a long time. So I'm pretty sure that file transfers through the console port are not supported.

Is there a reason that you can't use the USB or Management Ethernet ports?

You can console copy the files but that would take FOREVER. You should be able to configure one of the other ports on the 7K and use it as a management port.

Are there any 5K's, 2K's or any other switches that are connected to your 7K's that can host the files? This will allow you to set the lower end switches as FTP servers and use them as jump points if they are capable.

Like Don suggested, use the USB port. That's what I do. This link describes the file systems and how to copy files, if you need that info.

The management port is the default for copying files.

copy flash ftp

Then follow the prompts.

The FTP server has to be on the management network.

Here's a link on configuring the mgmt0 port on a Nexus 7k: http://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/best_practices/cli_mgmt_guide/cli_mgmt_bp/connect.html#wp1055673

You can use FTP, TFTP, SFTP, or SCP to copy from a remote host. I don't have the patience to wait for the transfers to complete during a maintenance window, and I can't push files ahead of time, so copying from USB has always been my preferred option.
