Configuring different VLANs for Access Points and WLANs

dot1x — Mon, 12 Mar 2018 04:53:00 GMT

Hi All,

I'm new to Extreme wireless.
Could someone please assist how can we configure the following:

1. APs get the IP Address from Management Subnet.
2. WLANs users get the IP Address from different subnet than the APs.

Thanks.

Hey Moin,

By default, WiNG AP is configured with DHCP IP for VLAN 1 which is the native VLAN for ge1
For WLAN user to get Ip address from a different subnet, multiple ways can be done:

For externally hosted DHCP server >> You will need to specify the VLAN under WLAN configuration and allow the VLAN at the switchport, refer to this: How do I Create a WLAN on A WM Controller
If you wish to host the DHCP server at AP, you will need to first set up the DHCP server, then specify the VLAN under WLAN configuration and allow the VLAN at the switchport. You may refer to the following article on how to configure DHCP service: How to configure DHCP services using CLI on WiNG Access Points.

Hope this helps~!

Hi Madeline,

Thanks for your reply.
When you say WiNG AP is configured with DHCP IP for VLAN 1 which is the native VLAN for ge1.
It is the case when the switchport has no config on it? Correct me if I'm wrong?

If we want APs to get IP address from a different VLAN, say VLAN10 and WLAN users on VLAN20. Do we need to configure the switchport as a trunk port with native VLAN as VLAN10?

>> I'll assume that you are referring to AP int ge configuration, and the default behaviour is as below:
interface ge1
switchport mode access
switchport access vlan 1
interface vlan1
ip address dhcp
ip address zeroconf secondary
ip dhcp client request options all

2.If we want APs to get IP address from a different VLAN, say VLAN10 and WLAN users on VLAN20. Do we need to configure the switchport as a trunk port with native VLAN as VLAN10?
>> Yes, on top of that you will need to configured AP interface ge1 to allow VLAN 10 and VLAN 20
For example:
interface ge1
switchport mode trunk
switchport trunk native vlan 10
no switchport trunk native tagged
switchport trunk allowed vlan 10,20

Hi Madeline,

Thanks for the detailed response. I didn't know if we could configure the AP int Ge interface with switchport commands.

In my case I'd have to configure the following:

AP Ge Interface:
switchport mode trunk
switchport trunk native vlan 10
no switchport trunk native tagged
switchport trunk allowed vlan 10,20

interface vlan 10
ip address dhcp
ip address zeroconf secondary
ip dhcp client request options all

Switchport Config (Where AP is connected)

interface gi1/0/1
switchport mode trunk
switchport trunk native vlan 10
switchport trunk allowed vlan 10,20

The Switch Config:

interface vlan 10
ip address 192.168.10.1 255.255.255.0
ip helper-address

interface vlan 20
ip address 192.168.20.1 255.255.255.0
ip helper-address

Does it make any sense?

Dear Moin,

I am not sure about the switch that you are using, but from the WiNG AP side, the configuration looks correct
You can do a show IP interface brief on the AP to check the IP address that it is taking

Hope this helps

Assuming we have Cisco Switches.
Does the config look good?

Thanks.

We are sorry to hear that 🙂

It looks OK
just as a reminder.... you'd need a "no shut" on the VLAN interfaces
