How should it to be done? (switch and AP connection)

  • 1.  How should it to be done? (switch and AP connection)

    Posted Jun 06, 2016 07:25 AM

    Hi,

    First I would like to describe my switch connections (my idea, maybe wrong, please correct me if so):

    I have core switch L3, with 3 VLAN: 1,5 & 100 with ip 172.16.10.1/24, 172.16.5.1/24 & 172.17.0.1/16

    VLAN 1 is provided for device addressing. VLAN 5 and VLAN 100 is for clients, wired and wireless.

    To the core switch, I have connected:

    1) MS 2012 Server with DHCP service with ip address 172.17.1.2/16

    2) W-3200 Controller with ip address 172.16.10.254/24

    3) access switch L3 with ip address 172.16.10.5/24

     

    To the access swich (3) I have connected 4 AP

    My question is:

    Is it possible to configure DHCP and AP, that AP receives IP address from 172.16.10.0 network, and  at the same time the wireless clients receives ip addresses from 172.17.1.0 network?

    If you have an Aruba Controller and access points, the ip address of the access points does not matter, as long as it can reach the controller.  The user traffic is tunneled from the APs to the controller and the controller will bridge the user traffic to whatever VLAN you specify.  So to recap:

     

    - Trunk all user VLANs to the controller using the layer 3 switch

    - Define all of the VLAN numbers on the controller

    - Make sure the access points can reach the controller's management ip address through any type of discovery (dhcp option, dns, broadcast)

    - Create a WLAN with the WLAN Wizard that puts users on the VLAN that you want them to be.

    - User traffic will be tunneled from the AP to the controller and bridged to whatever VLAN you have defined.

    May I ask some more questions?

    1) Can I assign all 4 ports (W-3200 have 4 1Gb ports) for all created VLANS on controller?

    3) Do I have to configure each port on controller as trunk port and assign all created on controller VLANs?

    4) Do I need to create separate WLAN for each VLAN?

     

    Best regards

    You can configure a single port on the controller as a trunk and trunk all of your VLANs to that port.  You would configure your layer 3 switch the same way.

    How to assign only 1 port for VLAN?

    Now I have:

    (W3200CTRL) (config) #show vlan

    VLAN CONFIGURATION
    ------------------
    VLAN Description Ports AAA Profile
    ---- ----------- ----- -----------
    1 Default GE1/0-3 Pc0-7 N/A

     

    I would like to assign only port no 0 to VLAN 1. I try this: 

     

    (W3200CTRL) (config) #interface gigabitethernet 1/3

    (W3200CTRL) (config) #no switchport access vlan

     

    but I still have ports 0-3 for vlan 1
