Error writing TFTP (Timed out attempting to connect) [FAILED]

Dilrajk57

I am trying to take backup of my ASA through tftp.

Command: ASA01/Hyb(config)# write net 172.24.50.9:/Test-561.tmp

Response: Building configuration...

                      INFO: Default tftp-server not set, using highest security interface Cryptochecksum: ******************************** !

%Error writing tftp://172.24.50.9 //Test-561.tmp;int=inside (Timed out attempting to connect) [FAILED] 

 

TFTP server is installed in Linux, tftp is working fine as I am able to take backup of other ASA which is in the same network.

 

Also after executing this command,  Test-561.tmp is created in TFTP directory but with size 0

  

Your help will be appreciated.

The error is "Timed out attempting to connect", so you have to verify connectivity between the ASA's inside interface and the tftp server. Apply a capture on the ASA's inside interface as below to verify what happen's when you run the backup command:

 

capture capi interface inside match ip host <inside-interface-ip> host <tftp-server-ip>

 

Run the test again and type following command:

 

show capture capi

Thanks Rahul for your quick response!

I have tried as you mention and here is what I got:
After configure "capture capi interface inside match ip host 10.51.23.7 host 172.24.50.9"
and then try backup activity.
ASA01/Hyb(config)# show capture capi


0 packet captured

0 packet shown

ASA01/Hyb(config)#

I beleive that there is no connection between inside interface and TFTP.

As per the Network, I need to use management interface for taking backup through TFTP.
Also I have checked, the connection between management interface and TFTP is fine.

It is my request to you, If possible, can you please tell me how can I configure management interface for this?

Try this:

 

hostname(config)# tftp-server <management-intf name> 172.24.50.9 /Test-561.tmp
hostname(config)# write net
