T42G VLAN settings for PC VLAN

[Uwe]

Hi,
we are new to Yealink phones. We want to use a T42G connected to VLAN 41 und thru the phone a PC connected to VLAN 31.

The Switches are HPE / aruba HP 2530-48G-PoEP Switch (J9772A)

the phone: Firmware Version 29.80.150.2
Hardware Version 29.1.0.0.0.0.0

We tried:
switchport VLAN 41 untagged, VLAN 31 tagged
switchport VLAN 41 tagged, VLAN 31 tagged
Phone:
WAN port disabled / enabled, VID 41
PC Port diesbled / enabled, VID 31

In some cases the PC gets a IP address from VLAN 41, or apipa address

In no config it gets an IP from VLAN 31.

What is the correct configuration on the switch and the phone?

Thanks
Uwe
