Thanks for your help :)

Hello,

Please try port link-type trunk for you Cisco Phone_PC connection, such as:

interface GigabitEthernet1/0/1

 description Cisco VoIP Phone_PC_connected
 port link-type trunk
 undo port trunk permit vlan 1
 port trunk permit vlan 92 102
 port trunk pvid vlan 102
 undo voice vlan mode auto
 voice-vlan 92 enable
 lldp compliance admin-status cdp txrx

Main difference in your config is that, here PC Data traffic is untagged. Voice vlan is tagged vlan.

Having LLDP-MED/CDPv2 working, you don't nee d to use OUI anymore.

Here is the example reference about LLDP_MED/CDPv2:

Hi,

Did you have a chance to check how it works with trunk port?

this is  present config   Use it without problems  Symptoms to watch for a while

Thank You

I have a CP-7940G version 1 and it will not even power on. What was the exact model of the 7940G phone you used? CP-7940G? Was it version 1 or version 2? Do you have the phone's firmware by chance? Also, what PSE firmware were you running?

I have a 7941G-GE V02 and it powers on just fine.

On another note, per this comment I required the below line to be added to my port config in order for the phone to register on the right VLAN.

• lldp tlv-enable med-tlv network-policy 95

Not sure about additional LLDP-specific line required but the fact is Comware just "emulates" CDPv2 in/out packets. So this is the case only for switches different than CISCO vendor. without native CDPv2 protocol implemented.

A am right?

Ok, here is the final explanation from HPE R&D Team:
