Reason: The status of root bridge cannot be kept because a switch with a higher priority on the network becomes the root bridge.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.4

hwMstpiPortRootGuarded

When the port of root bridge protection receives packets with higher priority, it triggers alarm.

Reason: A switch with higher priority and out of the root bridge protection circle attempts to preempt the status of the root bridge.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.5

hwMstpiPortBpduGuarded

• hwMstpiPortIndex

• ifName

When the BPDU guard port receives the BPDU packets, it generates alarms.

Reason: An edge port enabled with the BPDU guard function receives BPDUs.

Advice: The port receives BPDU packets that are likely to be hostile attack ones. The port is shut down at this time and needs to be manually restored by NMS administrators.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.6

hwMstpiPortLoopGuarded

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.7

hwMstpiEdgePortChanged

• hwMstpiStpPortEdgeport

• ifName

The BPDU guard is not enabled on the edged-port. When the edged-port receives a BPDU packet, the edged-port attribute will be disabled.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.15

hwMstpiTcGuarded

hwMstpiBridgePriority

After the TC guard function is enabled for the MSTP process and the number of TC BPDUs received by an MSTI in a unit time exceeds the threshold, the subsequent TC BPDUs are not processed until the TC guard time expires.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.16

hwMstpProTcGuarded

• hwMstpProTcGuard

• hwMstpProInstanceBridgePriority

After the TC guard function is enabled for the MSTP process, the TC BPDUs, which are received after the number of TC BPDUs received by an MSTI in a unit time exceeds the threshold, are processed after the TC guard time expires.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.17

hwMstpProRootChanged

hwMstpProInstanceRootPort

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.18

hwMstpProNewPortStateForwarding

• hwMstpProNewPortState

• ifName

When a port belonging to the MSTP process enters the forwarding state, an alarm message is generated.

Cause: A new link is added to the network.

Solution: Check the cause of the network topology change and check whether a fault occurs on the backup link.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.19

hwMstpProNewPortStateDiscarding

• hwMstpProNewPortState

• ifName

When a port belonging to the MSTP process enters the block state, an alarm message is generated.

Cause: A link is removed from the network.

Solution: Check the reason for the network topology change and check whether a fault occurs on the link.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.20

hwMstpProNewBridgeLostRootPrimary

hwMstpProInstanceRootType

When the MSTP process stop functioning as a root bridge, an alarm message is generated.

Cause: The MSTP process can no longer play the role of the root bridge because another MSTP process with a higher priority becomes the root bridge.

Solution: Reduce the priority of the new root bridge on the specified MSTI if you do not want another MSTP process to function as the root bridge. On the contrary, delete the setting of the original root bridge on the specified MSTI if you want the new MSTP process to function as the root bridge.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.21

hwMstpProNewPortRootGuarded

• hwMstpProNewPortState

• ifName

When a port enabled with the root guard function on the root bridge receives a packet of a higher priority, an alarm message is generated.

Cause: An MSTP process attempts to compete for the role of the root bridge.

Solution: Reduce the priorities on the specified MSTI of all MSTP processes on the device. Alternatively, reconfigure the root guard function for the port.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.22

hwMstpProNewPortBpduGuarded

• hwMstpProNewPortState

• ifName

When a port enabled with the BPDU guard function of the MSTP process receives BPDUs, an alarm message is generated.

Cause: An edge port enabled with the BPDU guard function receives BPDUs.

Solution: Manually restart the port because the port is shut down under the attack of BPDUs.

This object is implemented as defined in the corresponding MIB files.

1.3.6.1.4.1.2011.5.25.42.4.2.23

hwMstpProNewPortLoopGuarded
