Hello Experts,

Re: NO DHCP after connected to WIFI

Is the WLAN at site B in tunnel or bridge mode?


Cheers

Re: NO DHCP after connected to WIFI

Ok. How are your AP switchports configured? Trunk? Access?

What VLAN is set in your VAP?

What VLAN is set here for site B APs: AP-Group> AP> System Profile> Native VLAN

AP are access type, vlan 300, native vlan 1, the AP IP is on vlan 320 which is ip 192.168.32.1/23

Re: NO DHCP after connected to WIFI

Generally, when you set your VAP to bridge mode you either:
- bridge traffic at your AP untagged
- bridge traffic at your AP tagged

If you want your Wi-Fi traffic to exit your AP untagged (e.g. on the same subnet as your AP) set your VLAN to 1 in your VAP.

If you want your Wi-Fi traffic to exit your AP tagged (e.g. on a different VLAN/subnet as your AP) set your VLAN to 300 in your VAP & configure your switchport your AP is patched into as a trunk port with native VLAN 320 (AP VLAN) & tagged VLAN 300 (Client VLAN).

Re: NO DHCP after connected to WIFI

i set the native vlan to 300, on profiles, I'm getting ip from VLAN 320 which is 192.168.32.1/24 but my SSID is on VLAN 300, the DHCP IP should be 192.168.30.1/24, shall the VLAN on the interface have an IP?, my switch port has default native VLAN 1, I have several VLAN on it, 10 in total, SITE A have VLAN 106 as management VLAN, all AP is on it, on-site A everything works perfectly, each SSID can get ip from their respected VLAN. should I still change the native VLAN of my switch to 300? I have configured only one port for all these VLAN.

Re: NO DHCP after connected to WIFI

If the VLAN set in your VAP matches the VLAN set here: AP-Group> AP> System Profile> Native VLAN then the traffic will exit the AP untagged which sounds like what is happenning.

To fix it do this:
Set this to 1: Sita B AP-Group> AP> System Profile> Native VLAN
Set the VAP VLAN to 300.
Ensure the switchport the AP is patched into is configured as a trunk and VLAN 300 is tagged.

Re: NO DHCP after connected to WIFI

The VLAN 300 and 320 are

 

found at site B, on SITE A, core switch should I  tagged VLAN 320 and 300 to the trunk that connects the master controller?
