First,

I should understand vlan configuration (please find below) Should i understand all ports trunk for vlans ?
What is the difference between unTagPvidOnly,unTagAll,tagAll. Thank you all !

vlan ports 1-2 tagging unTagPvidOnly  filter-untagged-frame disable filter-unre
gistered-frames enable priority 0
vlan ports 3-6 tagging unTagAll  filter-untagged-frame disable filter-unregiste
red-frames enable priority 0
vlan ports 7 tagging unTagPvidOnly  filter-untagged-frame disable filter-unregi
stered-frames enable priority 0
vlan ports 8-22 tagging unTagAll  filter-untagged-frame disable filter-unregist
ered-frames enable priority 0
vlan ports 23-24 tagging tagAll  filter-untagged-frame disable filter-unregiste
red-frames enable priority 0
vlan ports 25-26 tagging unTagAll  filter-untagged-frame disable filter-unregis

Switchport mode access = untagall
Switchport mode trunk = tagall

Untag PVID only means the base VLAN that patches the PVID is not tagged, but any subsequent VLANS assigned to the port will be tagged.
So, looking at port 1 for instance, untag PVID only, VLAN 2 is untagged, while VLANS 200,250,300,350 are all tagged on the same port.

Hello,

Many thanks for your explanation, I understand that there is a dual-mode form here. A port allows tag and untag traffic at the same time. Is that true?

Also i m a little confused that part.

vlan members 1 5-8,22
vlan members 2 1-4,23-24

vlan ports 1-6 pvid 2

1-6 port assigned access for vlan 2 but also 5-8 assigned access for vlan 1. Am ı missing something?

vlan ports 1-6 pvid 2
vlan ports 7-8 pvid 1

That is your base VLAN.  In an untagpvidonly configuration, this is the 'access' mode VLAN.

vlan ports 1-2 tagging unTagPvidOnly  filter-untagged-frame disable filter-unre
gistered-frames enable priority 0
vlan ports 3-6 tagging unTagAll  filter-untagged-frame disable filter-unregiste
red-frames enable priority 0

Based on these lines, ports 1 and 2's PVID's are definitively untrunked.  However, ports 3-6 are untag all, so the only VLAN that will pass any traffic on those ports is VLAN 2.

vlan members 1 5-8,22
vlan members 2 1-4,23-24

All ports with members in VLAN 1 and VLAN 2.  Let's just focus on ports 1-4 for now.  Their PVID and VLAN ID match with a VLAN ID of 2. 

vlan members 200 1-7,9-12,23-24
vlan members 250 1-12,15-16,19-24
vlan members 300 1-7,9-12,23-24
vlan members 350 1-12,15-16,19-24
vlan members 400 1-7,9-12,21,23-24

This shows a configuration problem.  Remember, ports 1 and 2 have PVID of 2 and are set to untagpvidonly.  So, VLANs 200, 250, 300, 350, and 400 are tagged onto those ports and are fully accessible if the other side is configured the same.  But, ports 3-6 are set to untag all.  This shows someone attempted to tag additional VLANS to those ports.  Since they did not change the tagging method, none of those VLANS can be seen on the other side of a link to those ports.

Hope that helps!
