I'm using two sg 300 switch (Fw 1.1.1.8) and I configured vlans for data and phone.
Enabling voice lan, dynamic voice vlan, the option Enable Thelephon OUI is grayed.
I think that this is related to LLDP and CDP setting's, but I'm not able to discovery how.
How to enable thelephon OUI? where more info?.
Thanks,
Fabrizio

Hi Fabrizio,
Upgrade the switch to the latest firmware 1.1.1.8
Click on disable; second option under OUI Telephone and click apply. After this you should be able to enable Telephone OUI

Hello,
Go to Voice VLAN-->Properties (under which go to dynamic Voice Vlan settings)
First click disable and then click Apply to apply the configuration; now click second option Enable Telephony OUI to enable it.
Cheers

Sorry for my late reply.
The suggestion seem correct but, in my case, disabling the automatic voice vlan hang the switch. My switch is configured as layer 3 and is the main router of my network. If the switch is configured as layer 2 this dos not happen. I’ve contacted the Cisco support for more help and I’m waiting there response.

I have experienced weird behaviors as well. What I did is as following.
Disable smartport:
Enabled Smartport by Auto Voice VLAN and *:
Maybe that might help.

Hi Fabrizio,
Thanks for your reply. Please answer my question below to troubleshoot the issue further:
1) From your reply got to know that the device hangs when you enable telephony OUI option. Does it mean all the devices connected to it are not responding? Or the GUI itself hangs and you are unable to choose any options in it?
2) Can you briefly explain me what are the devices that are connected to switch. Did you add devices connected to the switch, first three octects of mac address in telephony OUI table?
3) Did you configure an interface connected to your switch to be a candidate port of the telephony OUI-based voice VLAN?
I will be more happy to know if you already got response from support team and are you able to resolve your issue? If not, please answer above question to look into the issue further.
Thanks,
Fabrizio

Hi Jyotshna,
The switch is configured layer 3 . I have other SG-300 switch on the same lan, but layer 2: on these switch I don’t have any issue.
I have scheduled more test next days, on lunch break, and I wont to use the serial port to see if I have more info.
I'm working with Cisco Support for this issue.
Thanks for your help,
Fabrizio
