Aruba IAP 225 LACP - GRE Question

[ Edited ]

Hi There,

 

NOTE: My main question is at the bottom

 

 

We have multiple sites with multiple Aruba IAP 225's in a Master/Slave setup and we would like to utilize the 2'nd ethernet port for increased throughput.

 

As a test to get things started we have a single Netgear GS724T Switch with 1 Aruba IAP 225(On the latest firmware), I have configured the required ports on the switch as follows:

 

Port 1 = Uplink(Internet)

Port 2 = LAG Member

Port 3 = LAG Member

 

I have configured the LAG to use LACP(not Static), spanning tree is off and Admin Mode is on.

 

When I power up the AP, it work's fine as standalone, I can see that in the switch, in the LAG section it says "g2,g3 link up". When I ssh onto the AP i run "show lacp status" it shows as below:

My question is, what is the "AP LACP GRE Striping IP: 0.0.0.0" ?, I have tried to read up on this and am getting very confused at the explanations/tutorials I've seen. Do I need it ?, is what I've got above ok for LACP ?

 

Most explanations I've seen is where people have configured the GRE and LMS IP on a Aruba/Cisco switch of some sort.

 

Any help would be greatly appreciated.

 

Kind Regards,

You do not need the GRE striping IP in an Instant environment.

It is used in controller-based environments to allow switches to load balance traffic back to the controller(s)  using IP address.

Hi,

 

I think your capture looks good, yes gre is only for controller based.

 

NOTE:

 

If you want redundancy for your Instants,put an external power supply on it, at the moment (actual firmware) the iap 225 only supports PoE on eth0 if eth0 fails there is no power on the IAP, the only thing to came over this is an external power supply...

 

If test this, I have installed wifi with iap225 in critical places, where wifi must work and we put on as failover an external powersupply and make lacp on stack member1 and member 2 ...
