Firstly you need to enable "Reboot the switch using the backup image after upgrading is completed.".  You can try to test again. If the interface still become unavaillable, it‘’s recommended to get a screenshot and post here. And how long did the interface stays down?

@Andone 

 

It is still down since yesterday, i posted this about an hour into the downtime.

 

i'm sorry could you be more specific because none of that made sense to me. I need to reboot using a backup image?

 

EDIT: Ok i figured out what you meanth by booting to the backup image, .. did that makes no difference. To be clear only the management interface crashes, the switch keeps working. Not sure how to create a screenshot of that there's no error, the screen just dims out a bit and that's it.

 

 

Tried again with chromium rather then firefox and i noticed there that it hangs on 20%

 

 

 

Tried upgrading to the same version, also happens. Even when the version is the same it happens. Checked of for some reason the IP didn't revert back to 192.168.0.1, although it's in a vlan .. maybe checking the wrong vlan.

 

 

Is there a way to do this through tftp from ssh, .. because i've tried but can't make sense of the syntax

Figured out the syntax

 

T1500G-10PS#firmware upgrade ip  10.13.17.12 file firmware.bin                 
 It will only upgrade the backup image. Continue? (Y/N):Y
 Loading tpImage...
Failed to initialize TFTP.

 

Not sure what I did wrong there.

 

 

From linux terminal

 

tftp
tftp> connect 10.13.17.12
tftp> get firmware.bin
Received 9003588 bytes in 7.8 seconds
tftp> quit

md5sum T1500G-10PSv2_en_2.0.3_\[20190509-rel36379\]_up.bin
0fa04cde9a6e5f6f0e67ea03321135dc  T1500G-10PSv2_en_2.0.3_[20190509-rel36379]_up.bin

md5sum firmware.bin
0fa04cde9a6e5f6f0e67ea03321135dc  firmware.bin

 

on the server (freebsd)

# md5 firmware.bin
MD5 (firmware.bin) = 0fa04cde9a6e5f6f0e67ea03321135dc

We can find the syntax in the CLI guide of the switch.

 

Syntax

firmware upgrade tftp ip-address ip-addr filename name

 

Parameter

ip-addr —— IP Address of the TFTP server. Both IPv4 and IPv6 addresses are supported, for Example 192.168.0.1 or fe80::1234.

name —— Specify the name for the firmware file

 

You need to have a TFTP server to store the firmware and please make sure the firewall will not block the access.

Tested once more what you said, put the tftpd in the same subnet so no firewalls.

 

T1500G-10PS#firmware up ip 10.13.15.45 file firmware.bin
 It will only upgrade the backup image. Continue? (Y/N):y
 Loading tpImage...

Correct syntax for firmware upgrade is

 

firmware upgrade ip-address <ip> filename <filename>

 

T1500G-10PS#firm
 upgrade              - Upgrade firmware through a TFTP server

T1500G-10PS#firm tftp
-----------------^
Error: Invalid parameter.

T1500G-10PS#firm
 upgrade              - Upgrade firmware through a TFTP server

 

again from linux terminal:

tftp
tftp> connect 10.13.15.45
tftp> get firmware.bin
Received 9003588 bytes in 5.2 seconds
tftp> quit

md5sum firmware.bin
0fa04cde9a6e5f6f0e67ea03321135dc  firmware.bin

 

Original file md5sum:

md5sum T1500G-10PSv2_en_2.0.3_[20190509-rel36379]_up.bin
