MSTP_1.3.6.1.4.1.2011.5.25.42.4.2.1 hwMstpiPortStateForwarding

Description

MSTP/4/PFWD:OID [oid] The port has been set to forwarding state. (InstanceID=[INTEGER], PortInstanceID=[INTEGER], PortID=[INTEGER], IfIndex=[INTEGER], PortName=[STRING])

A new link is added and the port enters the forwarding state.

Attribute

Alarm ID	Alarm Severity	Alarm Type
1.3.6.1.4.1.2011.5.25.42.4.2.1	Warning	communicationsAlarm(2)

Parameters

Name	Meaning
oid	Indicates the MIB object ID of the alarm.
InstanceID	Indicates the instance ID.
PortInstanceID	Indicates the ID of the instance to which the interface belongs.
PortID	Indicates the interface ID.
IfIndex	Indicates the interface index.
PortName	Indicates the interface name.

Impact on the System

The network topology will change.

Possible Causes

A new link was added to the network topology, and the network topology changed.

The network topology has changed, because a port may be up or down.

Procedure

View physical devices on the network to check whether new physical connections enabled with STP are added.
- If so, go to Step 2.
- If not, go to Step 3.
Check whether the added physical link is necessary.
- If so, go to Step 3.
- If not, go to Step 4.
Run the display stp [ process process-id ] [ instance instance-id ] [ interface interface-type interface-number | slot slot-id ] [ brief ] command to check whether the interfaces are consistent with the STP calculation results.
- If so, go to Step 6.
- If not, go to Step 5.
Correctly deploy the network topology, and then check whether the alarm is cleared.
- If the alarm is cleared, go to Step 6.
- If the alarm is not cleared, go to Step 3.
Collect alarm information and configuration information, and then contact technical support personnel.
End.
