Еще вот посмотрел в сторону каталиста 2950, к которому цепляется как VTP КЛИЕНТ 3548XL

та же команда, но на 3548XL
sh int fastEthernet 0/3 switchport

Switchport: Enabled
Administrative mode: trunk
Operational Mode: trunk

смущают строки Access Mode VLAN: 1 (default) на 2950
Access Mode VLAN: 0 ((Inactive)) на 3548xl
и вообще как то по разному раскидан здесь vlan 1. НО все же очень не нравиться что он идет в транк: Trunking VLANs Enabled: 1,18,1002-1005 - Каталист 3548XL
Trunking VLANs Enabled: 22,128-131,36,143 - Каталист 2950
