ExtremeWare XOS 11.5 supports only the Summit X450 family of switches and the BlackDiamond 8800 series switch.
STP Commands
Flags: (C) Topology Change, (D) Disable, (E) Enable, (R) Rapid Root Failover
(T) Topology Change Detected,
The following command displays STPD settings on an STPD named Backbone_st:
show stpd backbone_st
The following is sample output from this command:
Stpd: backbone_st Stp: ENABLED
