Reading manual may help
1)
vlan 10 name voice
vlan 20 name data

2)
You can only assign one vlan untagged but multiple tagged. You need to match your devices (VoIP) e.g. identify voice traffic by MAC or Lldp - med
vlan 20 port default 1/1
802.1q 10 1/1
3) i have no idea what you mean

You need to be a businesspartner to log into bpsw
If you are an end user, ask the seller of your switches to provide you with firmware.

You should be able to ping devices in the same vlan, means all devices at 1/2, 1/4, 2/2, 2/4, 3/2, 3/4 should be able to reach each other and should be able to reach the management IP 10.10.1.1 (if they have a matching IP/Netmask). Is your stack setup correct? What is the output of "show stack ...

I have done it ages ago. so search the forums here and see whether you find some "recover 6850" threads.
i have no full documentation here, so research first!

That should be the time, when the interface last changed. e.g link went up (or gone down)

i think it should do.
normally you would add the "vlan command" as well (necessary if you have multiple vlans. The "vlan_1" is just a name.
ip interface vlan_1 10.10.1.55 MASK 255.255.255.0 vlan 1

Seems like a file system error on the (built-in) Compact flash card.
I would try with fschk and newFS (search the forum here) as this otherwise may result in unwanted behavior/failing filesystem/corrupted data..

Never had that.. as this is more or less broken, you could try to do a recovery by NewFs (which will more or less format that flash) in hope that it recovers.. you need to upload firmware (desaster recovery from USB/Xmodem) afterwards.

Check the forum for more info. prepare for the worst

i think there was something like configuration apply <filename> but i think this will merge, not replace.

Normally you should see something on your serial console while rebooting.
The change you have done will not (Should not) result in such error.
Have you checked the Console cable on a different switch?

May either be dead Serial Console (cable) or a died switch. Both somewhat unlikely
