Indicates the index of a member interface.

TrunkId

Indicates the ID of a Trunk interface.

TrunkName

3.

A member interface left the LAG.

4.

The interface received the LACP packet sent from the interfaces on the same device.

Procedure

  1. Run the display this interface command on the corresponding interface to check whether the interface is Down.

    • If so, go to Step 2.

    • If not, go to Step 4.

  2. Run the undo shutdown command to check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 8.

  3. Check whether the physical link is faulty.

    • If so, go to Step 6.

    • If not, go to Step 4.

  4. Run the display eth-trunk command to check whether there is an interface on the local or remote end of the link leaving the LAG.

    • If so, go to Step 5.

    • If not, go to Step 7.

  5. Check whether the interface leaves the LAG normally.

    • If so, go to Step 8.

LACP_1.3.6.1.4.1.2011.5.25.41.3.3 hwLacpTotalLinkLoss

Description

LACP/2/TLL:OID [oid] Link bandwidth lost totally. (TrunkIndex=[INTEGER], TrunkIfIndex=[INTEGER], TrunkId=[INTEGER], TrunkName=[OCTET])

All the link bandwidths were lost.

Attribute

Alarm ID Alarm Severity Alarm Type
1.3.6.1.4.1.2011.5.25.41.3.3 Major operationalViolation(8)

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

TrunkIndex

Indicates the index of a Trunk.

TrunkIfIndex

The value of this object identifies the index of a Trunk interface.

TrunkId

Indicates the ID of a Trunk interface.

TrunkName

Indicates the name of a Trunk interface.

Impact on the System

Services are interrupted.

Possible Causes

A TLL trap was generated when all links between two devices were disconnected and packets failed to be forwarded.

Procedure

  1. Run the display interface brief command to check whether the interface is Down.

    • If the alarm is cleared, go to Step 2

    • If the alarm is not cleared, go to Step 4

  2. Run the undo shutdown command to check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 10.

    • If the alarm is not cleared, go to Step 3.

  3. Check whether the physical link is faulty.

    • If so, go to Step 7.

    • If not, go to Step 4.

  4. Run the display eth-trunk [ trunk-id [ interface interface-type interface-number | verbose ] ] command to check whether there are member interfaces in the LAG.

    • If so, go to Step 5.

    • If not, go to Step 8.

  5. Run the display trunkmembership eth-trunk trunk-id command to check whether the lower threshold of Eth-Trunk member links that can be Up in the LAG is correctly set. (An incorrect lower threshold causes the negotiation failure between the Eth-Trunk member interfaces.)

    • If so, go to Step 6.

    • If not, go to Step 9.

  6. In the Eth-Trunk interface view, run the least active-linknumber link-number command to correctly set the lower threshold of Trunk member links that can be Up. Then, check whether the fault is rectified.

    • If the alarm is cleared, go to Step 10.

    • If the alarm is cleared, go to Step 9.

  7. Repair the physical link and then check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 10.

    • If the alarm is not cleared, go to Step 4.

  8. Run the eth-trunk trunk-id command in the interface view and add the current Ethernet interface to the Eth-Trunk interface as required. Then, check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 10.

    • If the alarm is not cleared, go to Step 5.

  9. Collect alarm information and configuration information, and then contact technical support personnel.
  10. End.

The bandwidths of a link were partially lost.

Attribute

TrunkIndex

Indicates the index of a Trunk.

TrunkIfIndex

Indicates the index of a Trunk interface.

TrunkId

Indicates the ID of a Trunk interface.

TrunkName

Indicates the name of a Trunk interface.

Impact on the System

Part of services were interrupted.

Possible Causes

The number of the Eth-Trunk member links that were Up was smaller than the lower threshold value that was set, which caused the LAG to become Down. As a result, a PLL trap was generated.

Procedure

  1. Run the display interface brief command to check whether the interface is Down.

    • If so, go to Step 2.

    • If not, go to Step 4.

  2. Run the undo shutdown command to check whether the alarm is cleared.

    • If the alarm is not cleared, go to Step 3.

  3. Check whether the physical link is faulty.

    • If so, go to Step 7.

    • If not, go to Step 4.

  4. Run the display eth-trunk [ trunk-id [ interface interface-type interface-number | verbose ] ] command to check whether there are member interfaces in the LAG.

    • If so, go to Step 5.

    • If not, go to Step 8.

  5. Run the display trunkmembership eth-trunk trunk-id command to check whether the lower threshold for Eth-Trunk member links is set in the LAG; whether the number of Eth-Trunk member links that are successfully negotiated is smaller than the lower threshold for the Eth-Trunk member links that can be Up.

    • If so, go to Step 6.

    • If not, go to Step 9.

  6. In the Eth-Trunk interface view, run the least active-linknumber link-number command to correctly set the lower threshold of Trunk member links that can be Up. Then, check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 10.

    • If the alarm is not cleared, go to Step 9.

  7. Repair the physical link and then check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 10.

    • If the alarm is not cleared, go to Step 4.

  8. Run the eth-trunk trunk-id command in the interface view and add the current Ethernet interface to the Eth-Trunk interface as required. Then, check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 10.

    • If the alarm is not cleared, go to Step 5.

  9. Collect alarm information and configuration information, and then contact technical support personnel.

TrunkIfIndex

Indicates the index of a trunk interface.

TrunkId

Indicates the ID of a trunk interface.

TrunkName

Indicates the name of a trunk interface.

Impact on the System

Services are resumed.

Possible Causes

Parameters

Name Meaning

oid

Indicates the MIB object ID of the alarm.

TrunkIndex

Indicates the index of a trunk.

TrunkIfIndex

Indicates the index of a trunk interface.

TrunkId

Indicates the ID of a trunk interface.

TrunkName

Impact on the System

Part of services were resumed.

Possible Causes

1.

Because the number of trunk member links that could go Up through negotiation was below the minimum number of Up member links, the link aggregation group went Down, and thus the trap hwLacpPartialLinkLoss was generated. When the fault was rectified, the trap hwLacpPartialLinkLossResume was generated.

Procedure

  • This alarm message is informational only, and no action is required.
