Parameter
interface-list: Ethernet port list, containing multiple Ethernet ports and expressed
as interface-list = { interface-type interface-number [ to interface-type
interface-number] }&<1-10>. For detail descriptions of interface-type and
interface-number parameters, refer to the corresponding descriptions in Port
Command Manual. &<1-10> means that the preceding parameters can be
entered up to 10 times.
enable: Enables MSTP on the port.
disable: Disables MSTP on the port.
Description
Use the stp interface command to enable/disable MSTP on a switch port in
system view.
By default, if MSTP is enabled globally, it is enabled on every port. If MSTP is
disabled globally, it is also disabled on every port.
When MSTP is disabled, the corresponding port stays in forwarding state and does
not take part in any MSTI calculation.
CAUTION: If you disable MSTP on a port, a loop may be generated.
Related command: stp mode, stp.

# Enable MSTP on Ethernet 2/1/1 in system view.
