MSTP/4/PORT_STATE_DISCARDING

Message

MSTP/4/PORT_STATE_DISCARDING: The port has been set to discarding state. (InstanceID=[InstanceID], PortIndex=[PortIndex], IfIndex=[IfIndex], PortName=[PortName], PwName=[PwName])

Description

Specify that the status of the port STP becomes Discarding

Parameters

Parameter Name	Parameter Meaning
InstanceID	Indicates the instance ID.
PortIndex	MSTP port index.
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 alarm information and configuration information, and then contact technical support personnel.
