VLAN ID, PVID??

[dmayorgap]

Hi, i just got a HPE 1620 L2 switch, i have created 2 VLANS (10,20) and assigned untagged membership to access ports (top row to vlan 10 except port #1, and bottom row to vlan 20), also i setup a trunk port with these 2 vlans to connect to a router, everything is working great but i never modified the PVID field in any port, i'm confused about the concept of PVID, so i'm worried if its ok not to modify PVID or should i do it? But everything is working as expected, PC's from the 2 vlans connect to internet and everything.

Thanks

Regards,

David
