The edge port lost the attributes of an edge port after receiving BPDUs.

MSTP/4/TCGUARD:OID [OID] The instance received TC message exceeded the threshold will be deferred to deal with at the end of TC protection time. (InstanceID=[INTEGER])

After the TC protection was enabled on the device that was enabled with MSTP, the TC packets, which were received after the number of TC packets received in a specified period had exceeded the threshold, were processed after the TC protection time expired.

MSTP/1/PROTCGUARD:OID [OID] MSTP process's instance received TC message exceeded the threshold will be deferred to deal with at the end of TC protection time. (ProcessID=[INTEGER], InstanceID=[INTEGER])

After the TC protection of the MSTP process was enabled, the TC packets, which were received after the number of TC packets received by an instance had exceeded the threshold, were processed after the TC protection time expired.

MSTP/4/PRORTCHANGED:OID [oid] The root bridge of MSTP process has changed. (ProcessID=[INTEGER], InstanceID=[INTEGER], PortID=[INTEGER], PreviousRootBridgeID=[STRING], NewRootBridgeID=[STRING])

The root bridge changed. That is, a device became the root bridge or was not the root bridge any more.

MSTP/4/PROPFWD:OID [oid] The MSTP Process's Port has been set to forwarding state. (ProcessID=[INTEGER], InstanceID=[INTEGER], PortID1=[INTEGER], PortID2=[INTEGER], PortID3=[INTEGER], PortID4=[INTEGER], PortIDFlag=[INTEGER], IfIndex=[INTEGER], PortState=[INTEGER], PortName=[STRING])

The link status of MSTP process changed, and the port enters the forwarding state.

MSTP/4/PROPDISC:OID [oid] The MSTP Process's Port has been set to discarding state. (ProcessID=[INTEGER], InstanceID=[INTEGER], PortID1=[INTEGER], PortID2=[INTEGER], PortID3=[INTEGER], PortID4=[INTEGER], PortIDFlag=[INTEGER], IfIndex=[INTEGER], PortState=[INTEGER], PortName=[STRING])

The link status of MSTP process changed, and the port enters the Discarding state.

MSTP/1/PROROOT:OID [oid] MSTP process [process-id] is no longer the root bridge of the instance [instance-id].

The original MSTP process lost its status as a root bridge. Another MSTP process with a higher priority in the network replaced it and became the root bridge.

MSTP/4/PRORGSUP:OID [oid] The MSTP process's instance's ROOT-Protection port received superior message. (ProcessID=[INTEGER], InstanceID=[INTEGER], PortID1=[INTEGER], PortID2=[INTEGER], PortID3=[INTEGER], PortID4=[INTEGER], PortIDFlag=[INTEGER], IfIndex=[INTEGER], PortState=[INTEGER], PortName=[STRING])

An MSTP process with a higher priority outside the protection range of the root bridge attempted to become the root bridge.

MSTP/4/PROIVBPDU:OID [oid] The MSTP process's edged-port that enabled BPDU-Protection will be shutdown, because it received BPDU packet. (ProcessID=[INTEGER], InstanceID=[INTEGER], PortID1=[INTEGER], PortID2=[INTEGER], PortID3=[INTEGER], PortID4=[INTEGER], PortIDFlag=[INTEGER], IfIndex=[INTEGER], PortState=[INTEGER], PortName=[STRING])

The port of MSTP process enabled with BPDU protection and connected to the user received BPDUs. These BPDUs are likely to be attack packets from the user.

MSTP/4/PROLGEXP:OID [oid] The MSTP process's instance's LOOP-Protection port did not receive BPDU packets in prescriptive time. (ProcessID=[INTEGER], InstanceID=[INTEGER], PortID1=[INTEGER], PortID2=[INTEGER], PortID3=[INTEGER], PortID4=[INTEGER], PortIDFlag=[INTEGER], IfIndex=[INTEGER], PortState=[INTEGER], PortName=[STRING])

A port of MSTP process enabled with loop protection failed to receive BPDUs within a specified period, and was set to be in the Discarding state.

MSTP/4/PROEDGEDISABLE:OID [oid] When the port receives a BPDU packet, the edged-port attribute will be disabled. (ProcessID=[INTEGER], InstanceID=[INTEGER], PortID1=[INTEGER], PortID2=[INTEGER], PortID3=[INTEGER], PortID4=[INTEGER], PortIDFlag=[INTEGER], IfIndex=[INTEGER], PortState=[INTEGER], PortName=[STRING])

The edge port of MSTP process lost the attributes of an edge port after receiving BPDUs.

MSTP/4/PROLBDETECTGED:OID [OID] The MSTP Process's Port has been set to discarding state because of detecting loopback. (ProcessID=[INTEGER], InstanceID=[INTEGER], PortID1=[INTEGER], PortID2=[INTEGER], PortID3=[INTEGER], PortID4=[INTEGER], PortIDFlag=[INTEGER], IfIndex=[INTEGER], PortState=[INTEGER], PortName=[STRING])
