    Hi @cesar,

    Since you have created VLAN on Zyxel xgs-4526, you cannot use the VLAN trunk on it. The VLAN trunk only forwards unknown VLAN packets. Please set up the VLAN configuration correctly.

    Hi Zyxel_Melen ,

    The Zyxel xgs-4526 switch is working as a core where all the vlans to be used in the 
network were created, and for this reason the trunk is carried out between the two computers so that they establish communication and thus be able to distribute the dhcp of the floor vlan that corresponds

    Hi @cesar,
    Could you share your topology and current configuration with me? I can confirm what could go wrong.

    HI @Zyxel_Melen

Here I send you the topology, the laptop does not receive the DHCP offer 
although the MAC of the laptop is seen in the SW gs1910 and also in the SW CORE XGS4526.

    Hi @cesar,
    Thanks for the topology. However, I still need to check the configuration of GS1910 and XGS4526. Could you send the configuration to me via private message? Many thanks.
