How to configure PVST+ between x450-G2 and a CISCO

[Victor_Sumano]

I have a Cisco Switch as a Core, and I have 3 Stack of X450-G2 each ones, I have a lot of topology Changes, hundreds per day. The topology it’s a star so I have 1 port from the cisco to 1 port to each one of my stacks.

Cisco is configure with PVST+, so I need some help to understand how to configure in my EXOS switches.

All my trunk ports on my stacks are 1:52. the mac address for my root its the cisco, but I have MSTP configured

I’ve been reading a lot of gtac knowledge articles, and some other here, but each one, of course, are diferent. 

Can some one help me how to configure in my EXOS switches.

This is the actual status of stpd:

Hi Victor, 

Please see the following document: 

https://extremeportal.force.com/ExtrArticleDetail?an=000079698

Also, pelase be aware that we cannot add the native vlan because Cisco’s implementation is proprietary when it includes the native vlan.

Thanks
Brad
