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
