Parameters
enable
: Enables MSTP.
disable
: Disables MSTP.
interface-list
: Ethernet port list. You can specify multiple Ethernet ports by providing this argument in the
form of
interface-list =
{
interface-type interface-number
[
to
interface-type interface-number
] } &<1-10>,
where &<1-10> means that you can provide up to 10 port indexes/port index ranges for this argument.
Description
z
Use the
stp
command in system view to enable/disable MSTP globally. Use the
undo stp
command in system view to restore the MSTP state to the default globally.
z
Use the
stp
command in Ethernet port view to enable/disable MSTP on a port. Use the
undo stp
command in Ethernet port view to restore the MSTP state to the default on a port.
z
Use the
stp interface
command in system view to enable or disable MSTP on specified ports.
By default, MSTP is enabled both globally and on ports.
Note that:
z
After you enable MSTP, the device works in STP-compatible mode, RSTP mode or MSTP mode
depending on the MSTP mode setting, which is configurable with the
stp mode
command.
z
To control MSTP flexibly, you can use the
undo stp
enable
command to disable MSTP on ports
that are not intended to take part in spanning tree calculation and thus to save CPU resources.
z
After being enabled, MSTP dynamically maintains the spanning tree status of VLANs based on
received configuration BPDUs. After being disabled, it stops maintaining the spanning tree status.
Disabling MSTP on ports may result in data loops that can destabilize a network.
