Stp Mode - HP 3100 v2 Series Command Reference Manual

or removed, or migrated to the MSTP, RSTP, or PVST mode. Then, you can perform an mCheck
operation to force the port to migrate to the MSTP, RSTP, or PVST mode.
Suppose Device A running STP, Device B with no spanning tree feature enabled, and Device C
running MSTP, RSTP, or PVST are connected in order. Device B will transparently transmit the STP
BPDUs, and the port on Device C and connecting to Device B will transition to the STP mode. After
you enable the spanning tree feature on Device B, to run MSTP, RSTP, or PVST between Device B
and Device C, you must perform an mCheck operation on the ports interconnecting Device B and
Device C, in addition to configuring the spanning tree to operate in MSTP, RSTP, or PVST mode on
Device B.
The device operates in STP, RSTP, MSTP, or PVST mode depending on the spanning tree mode
setting.
The stp mcheck command is effective only when the device operates in MSTP, RSTP, or PVST
mode.
Configured in system view, the setting takes effect globally.
Configured in Ethernet interface view, the setting takes only effect 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.
