When try to define the root bridge, i like to set the priority to zero. But in this task we need the "spanning-tree vlan x root primary diameter" macro command to define the STP timers automatically. So my preferred solution would be:
Cat1(config)#spanning-tree vlan 541 root primary diameter 5 % This switch is already the root of VLAN541 spanning tree VLAN 541 bridge priority set to 8192 VLAN 541 bridge max aging time set to 16 VLAN 541 bridge hello time unchanged at 2 VLAN 541 bridge forward delay set to 12 Cat1(config)# Cat1(config)# Cat1(config)#do sh runn | inc spanning-tree vlan 541 spanning-tree vlan 541 forward-time 12 spanning-tree vlan 541 max-age 16 spanning-tree vlan 541 priority 8192 Cat1(config)# Cat1(config)# Cat1(config)#spanning-tree vlan 541 priority 0 Cat1(config)# Cat1(config)#do sh runn | inc spanning-tree vlan 541 spanning-tree vlan 541 forward-time 12 spanning-tree vlan 541 max-age 16 spanning-tree vlan 541 priority 0 Cat1(config)# Any comments ?
