I have 3  a new Access Points AIR-AP1852E-E-K9,

 

I am trying to transfer to mobility-express mode but it is show me the following error:

 

AP0CD0.F80C.1E70#ap-type mobility-express tftp://192.168.100.100/AIR-AP1850-K9-8-8-111-0.tar
Starting the ME image download...
It may take a few minutes to finish download.
If it is longer, please abort command, check network connection and try again

 

curl: (28) TFTP response timeout
transfer command failed
Image transfer failed. Please try again
AP0CD0.F80C.1E70#

 

Notes:

1) move files by tftp Server working well (tested with Cisco Switch 2960)

2) Wired0 Interface UP and ping able with tftp server

3) firewall disabled in tftp Server

4) after initialize command taken around 3 Minutes then give me that error

5) AP continuously rebooting (connected by POE to Cisco Switch 2960)

In the Cisco switch, is the command "tftp flash:AIR-AP1850-K9-8-8-111-0.tar" present? 

NOTE:  Don't use 8.8.111.0.  Use 8.5.135.0.

Either use 8.3.143.0 or 8.5.140.0 version software to upgrade.

- Enable logging on the tftpd server and check if there are any connections coming from the AP or not.

no i tested cisco switch with same tftp Server and .bin file

The error message states "TFTP response timeout". This means the AP is able to contact the TFTP server but the TFTP server is not handing out the file. This could mean the command "tftp flash:AIR-AP1850-K9-8-8-111-0.tar" may not be present.

I restart TFTP Serevr and used 8.5.135.0 Version then working fine, Thank you
