copy scp not working on Cisco Switch WS-C3850-24P

[yuccajt]

Recently i need to migrate our windows 2008 server that installed with ssh tectia.

All my laptop and checkpoint firewall were able to sftp to the new server successfully.

However, for cisco switch we have, i have tried several different devices but the copy scp wont work.

I tried to get file from sftp server to switch and vice versa.

copy flash: scp://XXX.XX.28.65:10022

copy scp://XXX.XX.29.49:10022 flash:

All will resulted in error below:

%Error writing scp://*****@XXX.XX.29.49:10022/test.txt (Undefined error)

I have tried to insert all parameter in 1 line (username, pwd) but still not working.

I also tried to insert the full file path and it also prompt me with undefined error.

Any idea what can i check further?

Hello,

what SCP software are you using (Putty is good option) ? 

Did you generate the rsa key on your switch ?

Check the link below:

I'm using SSH Tectia in the server.

I read the guide you posted earlier and seem like that not configured on the switch.

However the scp was working fine on the old server even without the mentioned config.

As a workaround, i tried the method suggested by enable the ip scp on the switch but seem like it still not working.

From the event log in the windows server, the scp traffic not even reaching the server as the log didnt captured any traffic.

Is there any other configuration apart from this ip scp server that required on Cisco devices?

I do a trace route to the next hop of the new server.

I encounter error:

exec request failed on channel 0
lost connection

Is this something i should check on the switch or server side?

Same like previous, the server log didnt captured any traffic.

Hello,

can you check the thread below ? Not sure if that is applicable in your case...

I know this is an older thread, but I figured others will experience this issue and this may help.  Try adding vrf Mgmt-vrf to the end of the command.
