Re: v1.5.8 Bug Reports and Comments

hi all, we have a number of WS-12-250 AC switches running 1.4.7 and 1.5.0 would it be a one step upgrade to 1.5.8?

If you do that you should have any trouble.

The problem is I just can't guarantee it would work. Usually it would, but it depends on the configuration of the switch and the network the switch is being used in.
What I would suggest in this case:
Download the configs from the client switches and load them into a test WS-12-250-AC switch you control on your bench with each firmware version.
Upgrade to the latest to see if anything goes wrong.
If something does, you can recover the switch with this tool and try it again incrementally instead.
If it still fails both ways and you can't find a safe way to upgrade it on your bench. Then your last safe option to avoid severe downtime would be to perform the upgrade on bench switches, configure them for the client, and replace them manually. I don't think this will be necessary, but it is an option.
Just to be clear, I'm not saying it will definitely fail, I'm just saying that if you want to be cautious, this is how I would recommend going about that.

Access the terminal for the switch via the web console, ssh, or serial console and run the following commands:
- Code: Select all
cmd
rm /tmp/new_temp_sensor
Then attempt the upgrade again.
Let us know how that goes.
