changing auto-voip type broke stack

[robfantini]

I had a stack of two of these:

!System Description "GSM7352Sv2 48-Port Gigabit Layer 3 Stackable Managed Switch with 2 10G SFP+ port, 10.0.0.53, 01.00.35"

!System Software Version "10.0.0.53"

early today I set up   '  auto-voip vlan '

after trying to switch to  'auto-voip protocol-based'    the stack froze.  

after power reset  the former master unit   has  no  link lites lit.

the former  secondary is runnig OK as master.

from prosafe web page ,  the bad switch is seen.    some of the vlan tags are not what they are supposed to  be [  some  T's changed to U ]

Does someone have a suggestion to fix the broken unit?

tech support by email told me how to solve this.

from cli:  reload

As expected  the switched restarted so office was ready for that.

More info:

before changing the auto-vlan type , I had saved the running config to start up , along with saving the text settings to tftp.

the one remaining switch is running good  - all vlans report working phones, printers and workstations.

ALSO from  java/web device view  - Back of switch :   Only the working switch  shows a stack connection slot green.    Power and serial are green on both

Hi robfantini,

Welcome to the community!

Could you please answer below quesitons, we need more detailed information for further analysis:

1. What's the auto-voip VLAN ID? Is it a new created VLAN or exsit VLAN?

2. Could you provide the auto-voip CLI command that you execute?

3. It's will be better if you can provide us the configuraiton of the Switch.

How do I send configure files from my Managed Switch to NETGEAR community moderators?

1. What's the auto-voip VLAN ID? Is it a new created VLAN or exsit VLAN?
   I am now using  'protocol based'  .  there is no vlan setting needed for that.

2. Could you provide the auto-voip CLI command that you execute?

no auto-voip vlan

auto-voip protocol-based

3. It's will be better if you can provide us the configuraiton of the Switch.

Hi robfantini,

Thanks for your immediately response.

Could you please also send us the tech-support file at the same time with the configuration file. We can check the detailed information for the freezing Unit.

1- I sent the startup-config in an email.

2- another thing I did after the two cli commands,   from web page at OUI Port Settings - I disabled Auto VoIP Mode  for all ports.

[robfantini]

I am unable to generate a tech support file.

I get this error:   Error! File is either empty or not found.

I tried http and tftp .

 Is there another way to create the file?

Hi robfantini,

You need execute command as 'show tech-support' by CLI mode(console port or telnet) at first, it will generate tech-support file.

[robfantini]

OK  sent another email with 'TechSupport'

and

the startup-config a few hours before I changed auto-voip mode.
