Problem:

Switch firmware upgrade failed from Airwave with the error message "Peer unreachable"
 

When trying to upgrade Aruba 3810 Switch from 16.04.0011 to 16.10.0002 using Airwave, the upgrade failed and we noticed the below error in telnet_cmds log of the switch in Airwave

>> copy tftp flash 129.237.235.55 KB_16_10_0002_swi_0.bin primary

previous cmd took 12.02560s

<< The primary image will be deleted.

<< Continue (y/n)?  y

<< Error in sending rq message.  Exceeded 5 retransmits.

<< 000M Peer unreachable.

In the event log of the switch we found the below error.

Firmware Upgrade: Error transfering the file.:  The primary image will be deleted.  Continue (y/n)?  y Error in sending rq message.  Exceeded 5 retransmits.

000M Peer unreachable           Downloading firmware failed   System

Verified the configuration of Aruba 3810 Switch, found that switch is configured as L3 device and ip source-interface is not configured for tftp application.

HP Switch # show running-config | inc source-interface

ip source-interface tacacs vlan 70

ip source-interface radius vlan 70
 

For pushing the image from Airwave to the Switch it uses tftp transfer, we have added ip source-interface to allow tftp transfer.

HP Switch # conf t 
HP Switch(config)# ip source-interface tftp vlan 70

Note : Here VLAN 70 is specified as the source ip address for tftp

After adding source interface we are able to push the firmware file from Airwave and the switch got upgraded successfully from Airwave
