you need to adjust the system defaults. Type the command "show default values" and look for the spanning-tree instances. On our Fastiron edge 12GCF i get this output: System Parameters Default Maximum Current spanning-tree 32 128 128 You can adjust these Values (Configmode) with the command: system-max spanning-tree 128 Hope it helps. cu thomas
