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 ?
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:
Staff, vlan 20
Student vlan 30
Guest vlan 40
Trunk untagged 10,
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.
