LLDP SoundPoint IP 331 Dell Powerconnect 3458

My company is in the process of switching over to VOIP and we're using Polycom SoundPoint IP 331 phones and Dell Powerconnect 3548 switches. We are trying to use LLDP to assign a VLAN to the phones however the phones will not take the LLDP configure broadcast by the switch. 


The phones have been updated to the latest firmware and LLDP is an option within the phone setup. We are currently manually setting the phones to the corresponding VLAN but in the future would prefer to have them grab what they need via LLDP instead.


My guess is that I may be missing some tlv information from my switch LLDP configuration but I can't figure out what. 


If anyone has any ideas on how to get LLDP to work with my phones and switches I would be very appreciative!


- Thanks
