N3K-C3172 // Problem when trying to perform a tftp copy: bootflash:

[jmhalegre]

Hi team,

I have a problem with a N3K-C3172TQ-XL, when I try to perform a copy tftp: bootflash: I get the following error:

SWPSJCPDCPDN3A1# copy tftp: bootflash:
Enter source filename: nxos.9.3.12.bin
Enter vrf (If no input, current vrf 'default' is considered):
Enter hostname for the tftp server: 10.140.8.86
Trying to connect to tftp server......
TFTP get operation failed:Permission denied
SWPSJCPDN3A1#

What can this be due to?

Thanks & Best Regards,

Juanmi

TFTP get operation failed:Permission denied - access issue or the file in the right location ( most of the time the file expect to be in root folder)

check any ACL in the TFTP check is the Nexus IP allowed ?

check is the TFTP working or not copy the config to TFTP see if that works ?

Hi Balaji.bandi,

I just ran the following test, and it worked correctly.

SWPSJCPDN3A1# copy tftp: volatile:
Enter source filename: SWPSJCPDN3A1-running-config
Enter vrf (If no input, current vrf 'default' is considered):
Enter hostname for the tftp server: 10.140.8.86
Trying to connect to tftp server......
Connection to Server Established.

TFTP get operation was successful
Copy complete, now saving to disk (please wait)...
Copy complete.
SWPSJCPDN3A1# dir volatile:

There seems to be some kind of write permissions problem in the Bootflash:, which does not allow copying files.

Any idea why?

Thanks & Best Regards,
