Nexus 3548 Firmware upgrade issues


Hi All


This is the first time I'm doing a firmware upgrade on a cisco switch. I'm use to dell.

I've been trying to do this for a few days now and not sure where i'm going wrong.
I first started with the usb but then I found out that you need to run the "compact" flag on the end.

I'm using solar winds SFTP/SCP tool to get my nxos.7.0.3.I7.10.bin on to it.

I'm following the Cisco Upgrade path 
But i can't seem to get the image on there successfully.

It copies the file to 100% but then errors out saying 

dstnexus03(config)# copy scp://jeff@ . compact vrf management
jeff@'s password:
nxos.7.0.3.I7.10.bin 100% 940MB 8.6MB/s 01:50
lost connection
Scp Compact of /bootflash/./nxos.7.0.3.I7.10.bin failed
Error doing scp

when I do ping the scp server from my nexus I get "No route to host"
But server can ping nexus.
Both are on the same vlan.

I have features enabled:

feature telnet
feature bash-shell
feature scp-server
feature interface-vlan
feature dhcp
feature lldp

Not sure what I'm missing here?

what kind of SCP Server ? Linux ?


when you ping you need to use VRF management to reach SCP Server. Looks like your GRT table not aware SCP Server address


# ping x.x.x.x vrf management


You have 2 Options :




check ping is working and able to reach SCP server before proceed to copy

ssh user@scpserverip  (using VRFmanagement as source) see are you able to connect.


Option2 . Download simple TFTP tool

easy to transfer the files.

Thanks @balaji.bandi 
So the ping x.x.x.x vrf management gives me a ping result.

ssh: connect to host port 22: No route to host

but the scp should still work, right?

you need to use VRF as source as mention other post like below :


ssh admin@ vrf management

 - No , scp uses the same ssh-service on the remote target , 'No route to host' simply means the remote scp/ssh service can not be reached , did you try the ssh with specifying management vrf too ?


So it connects and asks for the password but after entering it I get a 

shell request failed on channel 0

This may be due to far end issue, what SCP server you have other side


Looks like this is more complicated for you, why not install simple TFTP and fix the issue.

                      > request failed on channel 0

  - Check logs on remote ssh/scp server, use perhaps other brand (e.g.) or fallback to tftp (less performant and secure)


Still trying to find where the logs are for this application.
Any one suggest an possible alternative for windows?
simple TFTP is a not working, I need to use scp as I need to apply the compact flag during the copy.

Hi All

I couldn't figure it out with solarwinds scp.
I've copied the nxos files to another nexus i have and running the update from there.
I appreciate the help.

yes if that working for you.
