Stp Mode - HP FlexNetwork 5130 HI series Command Reference Manual

In this case, you can perform an mCheck operation to forcibly transit the port to operation in the
original mode.
For example, Device A, Device B, and Device C are connected in sequence. Device A runs STP,
Device B does not run any spanning tree protocol, and Device C runs RSTP, MSTP, or PVST. When
Device C receives an STP BPDU transparently transmitted by Device B, the receiving port transits to
the STP mode. If you configure Device B to run RSTP, MSTP, or PVST with Device C, perform
mCheck operations on the ports that connect Device B and Device C.
The device operates in STP, RSTP, PVST, or MSTP mode, depending on the spanning tree mode
setting.
The stp mcheck command takes effect only when the device operates in MSTP, RSTP, or PVST
mode.
When the setting is configured in Layer 2 Ethernet interface view, it takes effect only on that
interface.
When the setting is configured in Layer 2 aggregate interface view, it takes effect only on the
aggregate interface.
When the setting is configured on a member port in an aggregation group, it takes effect only after
the port leaves the aggregation group.
