Cannot change default LAN or adopt by OC200
I'm having real problems here. I'm trying to replace a router on a current existing network with an ER7206 so I can exploit the centralised Omada SDN management interface. The Omada simply won't adopt the gateway into the current network.
I think this is because the ER7206 is expecting mangagement on the 192.168.1.0 subnet VLAN 1, but the controller is on 192.168.100.0 subnet VLAN 10. I've managed to 'find' and adopt the gateway using the Omada, but the adoption fails, or appears to succeed but actually hasn't - when unplugging and replugging the gateway from the network it shows as disconnected from the OC200. I think the solution is to manually put the gateway onto IP 192.168.100.1 VLAN 10 in standalone mode prior to adoption, so that the Omada controller can find it again after adoption / provisioning. All of the provisioning info is already configured on the OC200.
Summary:
Controller: 192.168.100.0 subnet, VLAN 10 connected to an untagged port on VLAN 10 on the switch (can't change this or it will lose communication with the EAPs it is controlling)
EAPs (x7): 192.168.100.0 subnet, management VLAN10.
ER7206 current: 192.168.0.0 subnet, VLAN1
ER7206 desired: 192.168.100.0 subnet, VLAN10
I can't change the default network on the ER7206. I see this:
When I attempt to edit the IP, VLAN and DHCP range for this network the system appears to accept it, then reboots redirecting the webpage to the correct IP, but the changes have not been saved and revert to the previous default. I am able to add a new LAN at this point with the correct IP/VLAN settings, but there is no way to make the new LAN the default, meaning that all untagged traffic into the gateway ports is on VLAN 1, and also the gateway doesn't accept management by the OC200 on VLAN 10. The OC200 still sees the gateway at the default IP and fails to communicate with it on the mangement VLAN (10).
Any ideas? I have searched the forums for a solution but I'm either inefficient at searching or none has yet been presented.
