Spanning Tree Protocol (STP)
To display the STP state of a port, use the following command:
show stpd <stpd_name> ports {<port_list> {detail}}
This command displays the following information:
• STPD port configuration
• STPD port mode of operation
• STPD path cost
• STPD priority
• STPD state (root bridge, and so on)
• Port role (root bridge, edge port, etc.)
• STPD port state (forwarding, blocking, and so on)
• Configured port link type
• Operational port link type
If you have a VLAN that spans multiple STPDs, use the
show vlan <vlan_name> stpd
command to
display the STP configuration of the ports assigned to that specific VLAN.
The command displays the following:
• STPD port configuration
• STPD port mode of operation
• STPD path cost
• STPD priority
• STPD state (root bridge, and so on)
• Port role (root bridge, edge port, etc.)
