Bonjour,
Je pense que c'est un bug de GNS3 mais j'ai pu me planter quelque part ...
En adressage statique j'ai une connectivité de bout en bout. Avec un VLAN par switch je n'ai aucun soucis à obtenir une IP, toute mes interfaces concernées sur ESW1 sont up.

Mes VLANS ont une config simple je ne vois pas de différence hormis les ports alloués. Le vlan 10 devient 1010 et le vlan 150 1150, j'ai dû un peu tricher pour pouvoir les sauver avec GNS3. Pour le reste je n'ai fait que créer les VLANS, leur attribuer une adresse de management, des ports et pointer mon serveur DHCP.
VLAN 1010 est tout seul sur son switch et reçoit ses IP correctement :
En revanche les pc sur les VLANS 1150 et 1151 ont des adresses APIPA.
