Question on setting up Auto Voice VLAN with Polycom phones on a SF 300-24P

[Kevin Tomomitsu]

Has anyone successfully setup an SF 300-24P to Automatically Assign a Voice VLAN to traffic recieved from a Polycom IP Phone? We have LLDP-MED enabled with a the Policy assigned to the port, along with the interface configured as a Trunk with the PVID set to the Data VLAN and Auto VLAN Enabled.

Hello,

Thank you for using the Cisco Support Community. My name is Nico Muselle and I am working for the Cisco Small Business Support Center.

Responding to your question, the only additional thing needed on your switch is the choice of either one of below configurations :

1. Assign the phone VLAN statically to the ports connecting phones.
   
   or
   
2. Enable Voice Vlan (and change CoS setting to 5), and add the telephony OUI's (first 3 octets of the MAC) of the Polycom phones. You might have to add a few different OUIs. This way, the switch will detect the phone OUI and add the switchport to the Voice Vlan.

The LLDP-MED network policy as you defined on the other hand, will be used to assign the VLAN to the phone automatically so you do not have to configure it manually on all phones.

So, in short, you can choose either of the methods above, in combination with the LLDP-MED policy and everythings should work just fine. If it doesn't, please let me know.

Hi Nico,

     Thanks for the configuration information. Based on the information you provided we have everything setup correctly, what we found was that LLDP-MED is not supported on the Polycom IP Phones unless they are upgraded to the SIP version 3.2. Thanks again Nico.
