Stp Loop-Protection - HP E4510-48G Command Reference Manual

Parameters
None
Description
Use the stp enable command to enable MSTP globally in system view, on a port in interface view, or
on multiple ports in port group view.
Use the undo stp enable command to disable MSTP globally or on the port(s).
By default, MSTP is enabled on all ports and globally.
Note that:
MSTP takes effect when it is enabled both globally and on the port.
Configured in system view, the setting takes effect globally; configured in Ethernet interface view,
the setting takes effect on the current interface only; configured in port group view, the setting
takes effect on all ports in the port group; configured in Layer 2 aggregate interface view, the
setting takes effect only on the aggregate interface; configured on a member port in an
aggregation group, the setting can take effect only after the port leaves the aggregation group.
After you enable MSTP, the device works in STP-compatible mode, RSTP mode or MSTP mode
depending on the MSTP mode setting.
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.
Related commands: stp mode.
