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 port ID.

IfIndex

Indicates the interface index.

PortName

Indicates the interface name.

Impact on the System

The network topology will be changed.

Possible Causes

1.

The network topology changes that the port changes from the Forwarding state into the Discarding state.

2.

A new link is added. After the topology calculation, the port enters the Discarding state.

Procedure

  1. 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.

  2. Check whether the added physical link is necessary.

    • If so, go to Step 3.

    • If not, go to Step 4.

  3. Run the display stp [ instance instance-id ] [ interface interface-type interface-number ] [ 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.

  4. 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.

  5. Collect alarm information and configuration information, and then contact technical support personnel.
  6. End.
