show spanning-tree interface
Displays the state of the Spanning Tree Protocol for all named port-channels or 1-gigabit Ethernet,
or 10-gigabit Ethernet interfaces.
Synopsis show spanning-tree interface [port-channel number | fortygigabitethernet rbridge-id/slot/port |
tengigabitethernet rbridge-id/slot/port | gigabitethernet rbridge-id/slot/port]
Operands port-channel number
Specifies the port-channel number. The number of available channels
range from 1 through 63 for standalone mode, and from 1 through 6144
for Brocade VCS Fabric mode. However, the channel can be assigned any
number from 1 through 6144.
fortygigabitethernet Specifies a valid 40-gigabit Ethernet interface.
rbridge-id Specifies the RBridge ID.
slot Specifies a valid slot number.
port Specifies a valid port number.
tengigabitethernet Specifies a valid 10-gigabit Ethernet interface.
rbridge-id Specifies the RBridge ID.
slot Specifies a valid slot number.
port Specifies a valid port number.
gigabitethernet Specifies a valid 1-gigabit Ethernet interface.

Description Use this command to display the state of the spanning tree for all named port-channels or1-gigabit
Ethernet,10-gigabit Ethernet, or 40-gigabit Ethernet interfaces.
Usage Guidelines The following describes the port roles, states and types:
• Port roles—root port, designated port, alternate port and backup port.
• Port states—discarding, learning, and forwarding.
• Port types—edge port (PortFast), point-to-point, and shared port.
The gigabitethernet rbridge-id/slot/port parameter is used only on Brocade VDX 6710,
Brocade VDX 8770-4, and Brocade VDX 8770-8 switches.
Examples To display information on a 10-gigabit Ethernet interface:
switch# show spanning-tree interface tengigabitethernet 1/0/0
