vlans dhcp status are not received

[ldnnet001]

Hello,

I am configuring vlan on sg300-20 in dhcp mode.

One  vlan that is directed connected to the adsl router get ip address and when I connect host to the ports in this vlan they also receive ip address and can go on internet.

The other four vlans dhcp status are not received.

Kindly help me check this. Thanks

Below is the config log:

Also i do not understand why the ip address is 0.0.0.0/32 because the dhcp server ip address is 192.168.3.1

Dear Customer,

Thank you for reaching Small Business Support Community.

In Layer 2 system mode, only the management VLAN can be configured with a static or dynamic IP address. In Layer 3 system mode, all the interface types (ports,LAGs, and/or VLANs) on the device can be configured with a static or dynamic IP. Configuring the device to work in either mode is performed in the Administration >System Settings page

When a DCHP Client starts a discovery process, it assigns a dummy IP address 0.0.0.0 before the real address is obtained. This dummy address has the status of “Not Received”.

Pretty much your problem should be solved by changing to Layer3 system mode.  Please let me know if anything comes up and/or if there is any further assistance I may help you with.

Kind regards,

Thanks for taking time to look into this issue.

The switch is already changed to layer 3 mode before creating the vlans.

If I may ask, will it make any diiference if I use dhcp auto config option or not. Thanks

Dear Customer,

Notice that switching from one system mode to another requires a mandatory reboot, and the startup configuration of the device is then deleted.

By default, the device is enabled as a DHCP client when the Auto Configuration feature is enabled so I would then suggest you to disable it, particularly if you do not have to download configuration files from a TFTP/SCP server.

I'll be looking forward to hear from you and thank you for your time on this matter.

Kind regards,

Hi, thanks for your response on auto configuration.
I attached the screenshots from the router
It is TP-Link Cable/DSL router TL-R860.

Remember the main issue is that only the direct connected (vlan5) on the router get ip address from the dhcp. The other vlans do not get ip address.
when i add port to valn and attche host they can go on internet.
