Virtual Controller Cluster Client Traffic Pattern

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)

Re: Virtual Controller Cluster Client Traffic Pattern

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?
