Hi Colin,
Thank you for your post. Yes, I understand that when the Vlan ID in the VAP matches with the Remote AP DHCP server VLAN, is when the Bridge/Backup users would get an IP address from the RAP's internal DHCP server.
However, my concern is even when the forward/operation mode is set to Bridge/Standard or Bridge/Persistent or Bridge/Always I notice users are getting an IP address from the RAP's internal DHCP server.
Is it possible for both the servers to Offer an IP address in the above mentioned forward/operation modes.
So my question is:-
1. Is that an expected behaviour? because the UserGuide says that RAP's internal DHCP will work only for Bridge/Backup SSID only.
Attached is a screen-shot of my Lab setup
1. We have two SSID's( SSID1 and SSID2) both set to Bridge/Standard mode.
2. The Wifi-client1 connects to SSID1 and the Wifi-client2 connects to SSID2.
3. I notice based on the wireshark captures of the client that the Wificlient1 gets DHCP Offer from the RAP's internal DHCP server as well as from the Local DHCP on the Switch.
4. But the Wificlient2 gets DHCP Offer only from the Local DHCP on the Siwtch.
5. The only thing that is different is that we have specified vlan20 as the "Remote-AP DHCP Server VLAN"
6. However, the UserGuide says "Remote-AP DHCP Server VLAN" --> VLAN ID of the remote AP DHCP server used if the controller is unavailable. This VLAN enables the DHCP server
on the AP (also known as the remote AP DHCP server VLAN). If you enter the native VLAN ID, the DHCP server is unavailable.
My next question is:-
2. So what happens if the Controller is available and if I enter the "Remote-AP DHCP Server VLAN", does it still enable the DHCP server on the AP?
