Model: TL-SG2008  
Hardware Version: V4
Firmware Version: 4.0.6

I have a TL-SG2008 v4.0 switch and 2 AP245 in my network. The switch is configured to be the DHCP server and it's not working as expected. the DHCP reservation is not being applied and the clients (wired and wireless) are getting different IPs everytime. 
 

I need these IPs to be static in order to make the automation work here. 

 

I've already tried to set a different range for DHCP IPs and the IPs on the DHCP reservation list in another one. Nothing worked.

Any advice?

Hi @JustMe79 

Thanks for posting in our business forum.

Have you tried to refresh the IP address on your device? And rebooted the switch?

 

If you are using the controller mode, there is no option to bind a static IP to a MAC. In standalone, you can do that in L3 features.

In the controller mode, the only option you can use is the fixed IP address but that is based on the Omada routers. This means the DHCP reservation is not gonna be effective in controller mode.

 

So, back to the DHCP reservation in standalone mode, can you illustrate how did you test it?

  @valverde-thiago 

have you referred to the user guide in the configuration of the DHCP server and reservation?

have you checked your network scheme and made sure there is no mistake in your scheme?

Same issue with a TL-SG2218 v1.0 software version 1.1.8

 

DHCP Server is working, every client get a new DNS-IP if I change it, but DHCP Reservations are not working.

 

I config the switch over an OC200.
