I have spanning tree set up on Switch -1 for my management vlan which is the root (Mgmt vlan is on all switches). I have 4 switches that do have the management vlan on them in addition to a SAN VLAN. Switch 1 does not have the SAN VLAN active. Is it possible to implement STP on the SAN VLAN for Switches 3,4,5,6 with lets say Switch 5 as the root? So Switch 1 is the root for Mgmt VLAN and Switch 5 is the root for VLAN 200. will this work?
