SG2016P gets ip address from non-management VLAN DHCP server

SG2016P gets ip address from non-management VLAN DHCP server

SG2016P gets ip address from non-management VLAN DHCP server
SG2016P gets ip address from non-management VLAN DHCP server

Model: SG2016P  
Hardware Version: V1
Firmware Version: 1.20.14 Build 20251031 Rel.72837

Our SG2016P is configured with VLAN 2 as the management VLAN and has a static ip on that LAN, where it is managed by the Omada controller. Yet the SG2016P also gets an ip address from a DHCP server on a non-management VLAN and serves up the web GUI on that non-management IP with a message saying "This switch is being managed by controller". Is there a config setting to prevent switch management on non-management VLANs? 

 

Also in our setup there is no reason for the switch to use a DHCP client. Is there a config setting to disable the DHCP client?  We configured the non-management VLAN network where the switch received an ip with a static ip address on a bogus LAN, yet the switch runs its DHCP client anyway and gets an ip regardless.

 

Thanks

If the switch is being managed by a controller on the management VLAN, there is no need to enable a switch interface on any other VLAN unless you are routing or providing DHCP services with the switch.

Hi  @jra11500 ,

 

Only the management VLAN (2) is enabled on the switch and it is assigned a static ip. Yet the switch still leases an ip from disabled VLAN 1 via the upstream DHCP server. It should not matter but disabled VLAN 1 is configured with a bogus static ip.

 

It seems the switch insists on getting an ip via DHCP regardless of which VLANs are enabled. Even when all VLANs are set to DHCP: None, the switch still leases an ip.

Followup: turned out to be an issue on our side. Switch is working exactly as we need. The routing table now only has Management VLAN (2) routes and the managment HTTP service is only available from VLAN 2.
