change stp mode on nexus 3064pq

[malmsteen81]

hi,

i have this question. on my network i have all switches aruba cx6300 and a pair of nexus 3064pq  (FW 7.0.3) connected on vpc.

now on all aruba switch the spanning tree is configured as MSTP and on nexus rstp.

So i'm in doubt if change on nexus the spanning tree to mst or disable (on nexus are connected vmware hosts and lacp from other switches). what would you do?

it is possible to disable globaly the spanning tree? and if i will move from rstp to mstp is enough the command 

spanning-tree mode mst

 or  i need to change other settings?

thanks

No 

You need 

Spanning-tree mode mst

Spanning-tree mst config 

revision <>

Instance <> vlan <>

These revision and instance must be same as Aruba SW
