Use the show spanning-tree interface command (Figure 115) and show spanning-tree summary command (Figure 116) to verify that STP is initially disabled, both on interfaces and globally: Force10 #show spanning-tree interface 1/0/1 Hello Time..................................... 0 Port Mode......................................

Figure 116 Example Output from show spanning-tree summary Command Use the show spanning-tree brief command (Figure 117) to determine current bridge characteristics: Force10 #show spanning-tree brief Bridge Priority................................ 32768 Bridge Identifier.............................. 80:00:00:01:E8:D5:A7:82 Bridge Max Age................................. 20 Bridge Max Hops................................ 20 Bridge Hello Time.............................. 2 Bridge Forward Delay........................... 15 Bridge Hold Time............................... 3 Figure 117 Example Output from spanning-tree brief Command 166 Spanning Tree
Use the show spanning-tree command to verify that STP has converged. In Figure 118, executing the command on three participating switches shows that they have merged into one spanning tree, selecting S50-1 as the root bridge: S50-1 #show spanning-tree Bridge Priority................................ 32768 Bridge Identifier.............................. 80:00:00:01:E8:D5:A7:82 Time Since Topology Change..................... 0 day 0 hr 0 min 19 sec Topology Change Count.......................... 3 Topology Change in progress....................

FALSE Designated Root................................ 80:00:00:01:E8:D5:A7:82 Root Path Cost................................. 20000 Figure 118 Example Output from show spanning-tree Command Bridge ID of this switch Bridge ID of root bridge chosen by all switches Bridge ID of root bridge chosen by all switches Bridge ID of root bridge chosen by all switches In Figure 118, all three switches point to S50-1 as the Designated Root (DR), by identifying the bridge ID (MAC address — 00:01:E8:D5:A7:82) of S50-1 as the DR. Note also that the root path cost on the DR is 0 (zero), while, on the two other S50s, the root path cost is 20000. SFTOS Configuration Guide, Version 2.5.2.0 167
