Cisco Nexus 7K and wireless controller

We have Nexus 7k's in our core running RPVST how do I connect the wireless controllers to the core and avoid spanning tree issues?  Controlers are running 5.0.4.9.  Two controllers in HA pair using VRRP for IP address used by access points (Aruba-master)

How are you trying to configure it , trunk or port-channel ?

Thank you

The controllers are configured with a trunk.  Each controller has a single trunk link to one of the core switches.

Re: Cisco Nexus 7K and wireless controller

From my own experience is better to turn off STP on the controller and let your uplink switches (Core or Distribution) do the stp calculation.

I have seen issues because aruba controller becomes root .

Re: Cisco Nexus 7K and wireless controller

So in the controller turn off STP on the ports connected to the cisco 7k switch?

Turn it off globally : (controller) (config) #no spanning-tree 

 

To be SURE you should probably open a TAC case and that way Aruba TAC engineers take a look at your config and provide you the best answer/solution.

Thank you

Re: Cisco Nexus 7K and wireless controller

I'll second the advice.

 

We're running Master and Local (rather than VRRP) but but connect to the Nextus 7K fabric.

 

With Spanning-Tree off on each vlan (missed the global trick) we were great until we added a VLAN and forgot to turn it off there.

Fortunately the STP block wasn't catastrophic and we were able to recover smoothly.

 

We now also turn it off globally.
