Disabling spanning tree on 7210 Controllers

We have two controllers (MODEL: Aruba7210), Version 6.5.4.2.

 

The core network that they are connected to is using MSTP. As the controllers only support RSTP and PVST, I think it may be best to disable spanning tree onthe controllers and let the core switches handle loop prevention via MSTP.

 

I would like to know the following:

 

1 - Is it possible to disable spanning tree entirely on the controllers - if so how?

 

2 - With spanning tree disabled, will the controllers forward BPDUs received on one port out of the other(s), or will they be dropped.

 

Thanks in advance,

Jon

That will turn it off globally and depend on your switches for loop detection.  This is typically a best practice.

Re: Disabling spanning tree on 7210 Controllers

Thanks for the quick answer to question 1.

 

I would still like to understand what the behaviour of the controller will be with spanning tree disabled. Will MSTP BPDUs coming in to a port on the controller be forwarded out of other ports, or will they be dropped?

It will be forwarded out of ports on the same VLAN.
