I’m trying to assign a static IP address for an AP121 but not successful.
The network is setup like this:
The router was setup with the port address in subnet 192.168.128.0/24
3 VLANs were assigned to the router port as -
VLAN2 in subnet 192.168.88.0/22
VLAN3 in subnet 192.168.93.0
VLAN4 in subnet 192.168.101.0
The router port is connected with a SR2024P switch, configured with some trunk ports (native vlan as 1), and some access ports (native vlan as 2, 3 and 4).
The Router and AP121 is connected to one of the trunk port of the SR2024P switch.
All access ports in the switch function correctly and a laptop can get the correct DHCP subnet after connecting to the access ports.
The AP121 also functional. A laptop can get the correct DCHP subnet address after connecting the SSIDs (with the corresponding user profile with VLAN assigned) broadcast by the AP.
So here are the questions:
We tried to assigned a fixed IP to the AP121 but not successful. It seems the AP only get the DHCP address under the port subnet (192.168.128.0) of the router.
When we tried to config the Static IP (Configure => Device Configuration as above screen dump), , like 192.168.128.5, it seems the device still stick with with DHCP IP address (192.168.128.80), and the device configuration panel show the static IP that we want to change under the Automatically Generate Interface IP Settings.
How we can configure the Static IP Address for the AP121?
Actually we wish to configure the Static IP Address under the VLAN 3 subnet (i.e. 192.168.93.0). Does it possible or the static IP address must follow the subnet of the Router’s LAN port address?
The reason why we have this question is, we found we can only configure the Static IP Address for the SR2024P switch under the 192.168.128.0 subnet. The SR2024P refuse to Update with a Static IP address under the 192.168.93.0 subnet.
Another question is, we found the AP121 can only function properly if we set it’s Management VLAN as 50. It seems the Management VLAN setting for the SR2024P switch and AP121 must be set with a VLAN ID that is not setup in the router in order to make the AP121 functional, otherwise the SSIDs of the Access Point will not get the assigned VLAN, and the devices that connect to the SSID will not be able to get the DHCP address under the assigned VLAN as the user profile VLAN setup in the SSID.
So what is the purpose of the Management VLAN setting. Is that a correct approach that we should always assign it with the VLAN ID that is not occupied by the network?
Thanks for the advise in advance.
