Stp Loop-Protection - HP 6125G Command Reference Manual

Parameters
None
Description
Use stp enable to enable the spanning tree feature globally.
Use undo stp enable to disable the spanning tree feature.
By default, the spanning tree feature is disabled globally and enabled on all ports.
Configured in system view, the setting takes effect globally.
Configured in Ethernet interface view, the setting takes effect only on the interface.
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 takes effect only after the port leaves
the aggregation group.
When you enable the spanning tree feature, the device operates in STP, RSTP or MSTP mode, depending
on the spanning tree mode setting.
When you enable MSTP, the switch dynamically maintains the spanning tree status of VLANs, based on
received configuration BPDUs.
When you disable MSTP, the switch stops maintaining the spanning tree status.
