Question about 3Com switches (pre-HP)
We have 2x 4500G switches here. Over the weekend, for some reason they lost all their settings related to fibre ports being enabled and link aggregation, but all other settings were fine.
Been racking my brain all day, and all I can think of is that all the settings that were lost, were recent changes, and seeing the 'Save configuration' button on the web interface makes me wonder whether settings will only take effect until power-off unless config is written to the switch? And we possibly had a brief powercut over the weekend.
I'm used to configuring HP switches and as far as I can remember you don't need to do this, hence why it has only just occurred to me.
