LLDP Agents supported on Cisco IP phones 6941 and 7841

Do Cisco IP phone 7841 and 6941 support all three agents of LLDP

(1. nearest bridge - MAC address 01-80-C2-00-00-0E

 2. nearest non-tpmr bridge - MAC address 01-80-C2-00-00-03

 3. nearest customer bridge - MAC address 01-80-C2-00-00-00)

If the connected switch has LLDP MED network policy enabled for nearest bridge agent and not for the other two agents, what should the ideal behavior be?

Our observation is:

6941 seems to be ignoring nearest non-tpmr bridge and nearest customer bridge LLDPDUs and accepts the VLAN from the network policy of nearest bridge LLDPDU.

7841 accepts the VLAN from the nearest bridge LLDPDU but resets upon receiving either nearest non-tpmr bridge or nearest customer bridge LLDPDU as these do not carry the network policy information.

Does 7841 expect all three LLDPDUs to carry the same information?
