    Hi,

     

    I want to know how is the traffic flow for Instant Cluster setup?

    Let say I have 3 IAP:

    IAP_1 - Virtual Controller IP = 192.168.0.10, AP IP = 192.168.0.10

    IAP_2 - Virtual Controller IP = 192.168.0.10, AP IP = 192.168.0.11

    IAP_3 - Virtual Controller IP = 192.168.0.10, AP IP = 192.168.0.12

     

    Client associate at IAP_2 & IAP_3 will the traffic goes back to IAP_1 first before goes to internet cloud or it will direct goes out to internet cloud ?

     

    Regards

    Michael

    It depends. Are you using the Instant cluster to NAT or are users being dumped directly onto a VLAN?

     

    Guest users being NAT'ed:  User traffic -> AP -> VC

    Traffic destined for corporate network via VPN (RAPNG):   Traffic -> AP -> VC -> IPsec tunnel

    Regular local VLAN configuration:   Traffic -> AP -> local network (switched)

    My architecture is this:

     

    VLAN:

    Management, vlan10

    Staff, vlan 20

    Student vlan 30

    Guest vlan 40

     

                                                             Trunk                                        untagged 10,

                                                                                                               tagged 20,30,40               

    Server-------------Core Switch----------------Access Switch-------------------------------Aruba IAP

    (DHCP)             (Layer 3 VLAN)                   (Layer 2 VLAN)                                      

     

     

    So, I guess it a Regular local VLAN configuration:   Traffic -> AP -> local network (switched). Am I right?

    According to your scnario your data traffic  go through Virtual controller. actually APs are layer 2 deivce if they have proper IP to connect Internet gateway they can reach internet without go though controller.

    you use controller manged dhcp, so you may have to use controller to NAT client IP.
