Setting up an IAP cluster

Hi guys,

 

I am going to setting up a cluster made up of 16 IAPs. The point is the IAPs are going to have static IPs, and their uplink management VLAN isn't the native but VLAN 800. The switch ports where their uplinks end are trunk ports and the allowed VLANs are 2, 3 and 4 for corporate WLANs and 800 for AP management. How can I do for configuring the master AP and the rest of APs pull its configuration in this scenario? I think if I configure an AP to be the master and I want the rest of AP pull its configuration, it is not going to work, because the uplink management VLAN by default is 0 or 1, and these VLANs are not allowed in the trunks. Do I need to configure the APs one by one? I attached a network topology image.

 

Regards,
Julián

Re: Setting up an IAP cluster

In that case you will need to configure each IAP individually and configure the IP address from ap console
https://community.arubanetworks.com/t5/Controller-less-WLANs/How-do-I-configure-a-static-IP-addreess-to-an-Instant-Access/ta-p/185590

The Master IAP will be automatically selected based on uptime on the network but you can configure the preferred master via cli

Re: Setting up an IAP cluster

Hi Julian,

 

If i understand correctly , IAP's need to be configured with static IP's belonging to vlan 800.

However, vlan 800 will be tagged on the uplink port (switch side).

 

If my understnading is correct, you can try the following:

 

1. Connect the IAP's to the switch.

2. Initially IAP can not tag any packets as uplink management vlan is set to 0 by default.

3. So, it will send DHCP DISCOVER packets on native vlan.

 

"As there is no DHCP service on the network, the IAP obtains an IP automatically within the 169.254 subnet.

 

4. The instant SSID should be available to connect a client.

 

Connect a wireless client to instant SSID & navigate to "instant.arubanetworks.com".

 

We should get the login prompt  for the WebUI. The default credentials are admin/admin.

 

5. Once you are logged into Web UI, you can assign static IP's to the IAP's & change their uplink management vlan to 800.

 

We need to reboot the IAP's in order for these changes to take effect.

So, once you have set static IP's/uplink management vlan on all the IAP's, you can reboot them from the Web UI.

 

Note: if possible, try these steps on 2-3 IAP's initially . If everything works as expected, you can congfiure the remaining IAP's accordingly.

Re: Setting up an IAP cluster

Why not use an external DHCP to assign IPs to the IAPs ?

Hi Victor,

 

It can't be. It is a requirement of customer to have static IPs and specific management VLAN for the IAPs to best control them.

Re: Setting up an IAP cluster

Hi Víctor,

 

You said by console, can't I configure the static IP for each IAP by the instant GUI?

Re: Setting up an IAP cluster

Hey, you can set a static IP from the GUI

Re: Setting up an IAP cluster

Hi,

 

I know how to set a static IP from the GUI, but I don't know if I can reach the instant GUI when the management VLAN for uplink is not the native but it is another (800 in my case).

Re: Setting up an IAP cluster

You can but the IAP needs to get an ip unless you can convert to standalone mode via cli

Re: Setting up an IAP cluster

Hi Victor,

 

Then you mean that the IAP needs to get an IP before I can reach the instant GUI and that the IAP can't get an IP when the management VLAN is not the default?

Re: Setting up an IAP cluster

Hi Victor,

 

Am I right on what I have stated in my last post?

 

Then you mean that the IAP needs to get an IP before I can reach the instant GUI and that the IAP can't get an IP when the management VLAN is not the default?

Julián
