Spanning-Tree Commands In the output below, VLAN 1 is a member of MST 1 and since switch ports e45 and e46 are static members of VLAN 1, the output below for MST 1 indicates that e45 is forwarding to the root of the STP domain and e46 is blocking and therefore the alternate path. VLAN 2 is a member of MST 2 and since switch ports e43 and e44 are static members of VLAN 1, the output below for MST 2 indicates that e43 is forwarding to the root of the STP domain and e44 is blocking and therefore the alternate path. Note: Results may be somewhat different in your specific environment. Just keep in mind that the purpose of the mstp-rstp feature is to isolate PVST Instances. When connecting the HP PC Blade Switch to any standards based Spanning-Tree infrastructure, this feature must be disabled and the switch must be reconfigured to interoperate using the appropriate IEEE Standardized Spanning-Tree Protocol. Example The following commands display spanning-tree information.
