System impact

The users connected to the port are disconnected.

Status control

CLI: Use the stp bpdu-protection command.

MIB: Set hh3cdot1sMstBpduGuard to true(1).

OFF

MIB: Set hh3cdot1sMstBpduGuard to false(2).

Object

OID (object name)	Description	Index	Type	Value range
1.3.6.1.2.1.17.2.15.1.1 (dot1dStpPort)	Port index.	dot1dStpPort	INTEGER	1..65535

Recommended action

To resolve this issue:

1.Verify that the downstream device is an endpoint device.

2.Check for possible attacks from other devices.

hh3cPortMstiLoopGuarded

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.8.35.14.0.6	An alternate port or root port does not receive a BPDU upon BPDU reception timeout.	Informational	Warning	-	OFF

Notification triggers

This notification is generated when an alternate port or root port does not receive a BPDU upon BPDU reception timeout. This might be because STP is disabled on the peer or the link is congested.

System impact

The port cannot forward traffic.

Status control

CLI: Use the stp loop-protection command.

MIB: Set hh3cdot1sMstiPortLoopGuard to true(1).

OFF

MIB: Set hh3cdot1sMstiPortLoopGuard to false(2).

hh3cMstiNewRoot

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.8.35.14.0.7	A new root bridge is elected.	Informational	Warning	-	OFF

Notification triggers

This notification is generated when a new root bridge is elected in the network. This might be because:

The bridge join a new network topology.

The priority of the bridge is increased.

The old root bridge fails.

The priority of the old root bridge is reduced.

System impact

The network topology changes, and traffic loss might occur.

Status control

CLI: Use the snmp trap enable stp new-root command.

OFF

CLI: Use the undo snmp trap enable stp new-root command.

● Verify the bridge priorities of the devices.

● Check for possible attacks from other devices.

hh3cMstiTopologyChange

Basic information

OID	Event	Type	Severity	Recovery notification	Default status
1.3.6.1.4.1.25506.8.35.14.0.9	The network topology changes after the spanning tree state of ports changes.	Informational	Warning	-	ON

Notification triggers

This notification is generated when the spanning tree state changes of ports cause network topology changes. This might be because:

A new link is added.

A port goes down and then comes up.

The device priority is modified.

The cost or priority of a port is modified.

System impact

The network topology changes, and traffic loss might occur.

Status control

This notification cannot be disabled.

Recommended action

To resolve this issue:

1.Check whether a link enabled with STP is newly added.

2.Check whether the device priority is modified.

3.If the issue persists, collect alarm information and configuration data, and then contact H3C Support for help.

hh3cPortMstiLostEdge
