MSTP/4/MSTPLOG_PROPORT_STATE_DISCARDING

Message

MSTP/4/MSTPLOG_PROPORT_STATE_DISCARDING: The MSTP process's port has been set to discarding state. (ProcessID=[ProcessID], InstanceID=[InstanceID], PortID=[PortID], IfIndex=[IfIndex], PortName=[PortName], PwName=[PwName])

Description

The port in the MSTP process entered the discarding state.

Parameters

Parameter Name	Parameter Meaning
ProcessID	Indicates the MSTP process ID.
InstanceID	Indicates the instance ID.
PortID	Indicates ID of the port in the MSTP process.
IfIndex	Indicates the interface index.
PortName	Indicates the port name.
PwName	Indicates the PW name.

Possible Causes

The network topology changed.

Procedure

1. View physical devices on the network to check whether a new physical link that has STP enabled is added.

If a new physical link that has STP enabled is added, go to Step 2.
If no new physical link that has STP enabled is added, go to Step 3.

2. Check whether the added physical link is necessary.

If the added physical link is necessary, go to Step 3.
If the added physical link is unnecessary, go to Step 4.

3. Run the display stp [ process ] [ instance instance-id ] [ interface interface-type interface-number | slot slot-id | vsi vsi-name pw ] [ brief ] command to check whether the interfaces are consistent with the STP calculation results.

If the interfaces are consistent with the STP calculation results, the alarm will be cleared.
If the interfaces are inconsistent with the STP calculation results, go to Step 5.

4. Correctly deploy the network topology, and then check whether the alarm is cleared. If the alarm persists, go to Step 5.

5. Collect log information and configuration information, and then contact technical support personnel.
