Hello Cisco Community.
I need to remotely copy a file from a switch to many others. I am getting the following error however when I use SCP with SCP server enabled on all switches:
*May 4 17:30:46.874: %SSH-3-BUFF_LEN_EXCD: Buffer Length exceeded %SSH-3-BUFF_LEN_EXCD: Buffer Length exceeded *May 4 17:30:46.874: %SSH-3-BUFF_LEN_EXCD: Buffer Length exceeded *May 4 17:30:46.874: %SSH-3-BUFF_LEN_EXCD: Buffer Length exceeded *May 4 17:30:46.874: %SSH-3-BUFF_LEN_EXCD: Buffer Length exceeded
I've used this command before without any issues on 9200/9300s but seems to fail with IE3200s:
Copy usbflash0://ios/ie3200/ie3x00-universalk9.17.03.05.SPA.bin scp://project:project@172.x.X.x://flash:ie3x00-universalk9.17.03.05.SPA.bin
Am I using the right command? Can someone also let me know how to use copy scp to remotely pull a file from a USB location or flash located on another switch?
Thanks in advance.

Issue was due to a coworker making windowing changes for file transfers for staging. I removed the setting below which resolved.
no ip tcp window-size 65535 no ip ssh window-size 65535
Can someone still assist with providing the correct command to pull files from a switch to another switch via SCP? Thanks.

Hello,
which IOS version are you running ? You could be affected by the bug below:
SSH session hangs if it is not closed properly
CSCva46459
Symptom:
SSH session hangs and doesn't get closed properly.
The below logs might be generated on the device:
%SSH-3-BUFF_LEN_EXCD: Buffer Length exceeded
In some situations the router might reboot unexpectedly with the below line in the crashinfo file:
IOSXE-WATCHDOG: Process = TTY Backgroun
Conditions:
If the ssh session is not closed properly
Workaround:
Close the session gracefully, or clear the line VTY's using the console of the router
Further Problem Description:
This bug also affects CBR8

Hi Georg,
I don't think it is related to the bug but a setting a coworker had applied to try and speed up file transfers. Here's the version:
xxnsw01#show version Cisco IOS XE Software, Version 17.03.05 Cisco IOS Software [Amsterdam], IE3x00 Switch Software (IE3x00-UNIVERSALK9-M), Version 17.3.5, REL
Do you know the command to scp a file from a switch from another? Here's the example that I use to copy a file to a switch but haven't figured out the reverse:
Copy flash://ios/9200/cat9k_lite_iosxe.17.03.04b.SPA.bin scp://user:pass@172.30.13.x://flash:cat9k_lite_iosxe.17.03.04b.SPA.bin
