Brocade Network OS Administrator’s Guide v4.1.1 - Manual (Page 431)

The gigabitethernet rbridge-id/slot/port operand is used only for the Brocade VDX 6710, Brocade
VDX 8770-4, and Brocade VDX 8770-8. The prompt for these ports is in the following format:
switch(config-if-gi-22/0/1)#.
switch(config)# interface tengigabitethernet 0/1
3. Enter the no shutdown command to enable the DCB interface.
switch(conf-if-te-0/1)# no shutdown
4. Enter the spanning-tree command to enable spanning tree on the DCB interface.
switch(conf-if-te-0/1)# spanning-tree shutdown
Configuring DiST
With respect to Distributed STP (DiST), the CLI commands to configure xSTP in the VCS mode are
exactly the same as the CLI commands in standalone mode. By default, all the ports are spanning tree
disabled. Server ports must be configured as an xSTP edge port.
NOTE
DiST is supported on the VCS edge ports only. DiST cannot be enabled on ISL ports participating in the
TRILL-based fabric within VCS. DiST does not update the port state of ISL ports.
xSTP can be enabled on the VCS by means of the protocol spanning-tree command. An interface
begins participating in the spanning tree once it is configured by the spanning-tree enable command.
Refer to
Configuring and managing STP and STP variants on page 412.
The following table describes the behavior of interface based on global and interface level configuration.
By default, spanning tree is disabled at the global and interface configuration levels.
