Unable To Upgrade Switch Firmware From 16.03 To Higher Version With Airwave


Aruba Switch Firmware upgrade from 16.03.x to higher version failing with Airwave



Uploaded 16.03.007 to Airwave using SFTP protocol and tried upgrade firmware from Devices > Manage page but it failed after few minutes.

In device event log we are seeing message Firmware Upgrade: Error transferring the file.
In device telnet_cmd log under /var/log/ap/ directory we are not seeing any log entries during this time.


In switch logging:

W 06/10/20 07:46:01 03311 sftp: User Aruba.Airwave: SFTP connection failure while connecting from

I 06/10/20 07:46:01 03318 sftp: User scpuser40887: File transfer from is in progress

I 06/10/20 07:45:58 00179 mgr: SME SSH from - MANAGER Mode

I 06/10/20 07:45:57 03362 auth: User 'Aruba.Airwave' logged in from to SSH  session

We can manually upload the file using external SFTP server.


Enabled compatible ciphers option from  AMPCLI > Configuration > SSHD > Use Compatible Ciphers,
After this, we are able to SFTP file to switch.

16.03.x is old code which supports old ciphers. 
If strict ciphers option is enabled in Airwave, it will not be able to communicate with the switch and file transfer fails.
