Use this command to display the blocked ports in a Spanning Tree.
| sid | (Optional) Displays blocked ports on a specific Spanning Tree. Valid values are 0 - 4094. If not specified, SID 0 is assumed. |
If sid is not specified, blocked ports will be displayed for Spanning Tree 0.
All command modes.
A port in this state does not participate in the transmission of frames, thus preventing duplication arising through multiple paths existing in the active topology of the bridged LAN. It receives Spanning Tree configuration messages, but does not forward packets.
This example shows how to display blocked ports on SID 1:
System(rw)->show spantree blockedports 1 SID Port --- --------- 1 ge.1.1 1 ge.1.3 1 ge.1.5 Number of blocked ports in SID 1 : 3
