show spanning-tree mst interface
Displays information for a specified interface for a Multiple Spanning Tree Protocol (MSTP)
instance.
Synopsis show spanning-tree mst interface [port-channel number |
tengigabitethernet rbridge-id/slot/port | gigabitethernet rbridge-id/slot/port]
Operands port-channel number Specifies the port-channel of the interface. 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.
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.
rbridge-id Specifies the RBridge ID.
slot Specifies a valid slot number for the interface for which to display
information for the MSTP instance.
port Specifies a valid port number for the interface for which to display
information for the MSTP instance.
Defaults None
Command Modes Privileged EXEC mode
Description Use this command to display MSTP protocol specific information such as Common and Internal
Spanning Tree (CIST) spanning-tree related information, information to each MSTP instance
(MSTI), and the state of the port specific to each MSTI.
Usage Guidelines 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 for the MSTP interface:
switch# show spanning-tree mst interface tengigabitethernet 5/0/1
