Description

L2IF/4/SLOT_MAC_LIMIT_ALARM:OID [oid] MAC address learning based on SLOT reached the limit. (L2IfPort=[L2IfPort], MacLimitVlanId=[MacLimitVlanId], MacLimitVsiName=[MacLimitVsiName], entPhysicalIndex=[entPhysicalIndex], aseTrapSeverity=[aseTrapSeverity], BaseTrapProbableCause=[BaseTrapProbableCause], BaseTrapEventType=[BaseTrapEventType], MacDynAddressLearnNum=[MacDynAddressLearnNum], MacLimitMaxMac=[MacLimitMaxMac], SlotName=[SlotName], DeviceName=[DeviceName])

The number of MAC addresses learned from packets on a board reached or exceeded the specified alarm threshold.

Impact on the System

If a slot-based MAC address learning limit rule is configured using the mac-limit slot slot maximum max rate interval action discard alarm enable command to limit the maximum number of MAC addresses that can be learned and discard excess packets when the maximum number is reached, all subsequent packets are discarded when the number of MAC addresses learned from packets on the specified board exceeds the value specified in max.

If a slot-based MAC address learning limit rule is configured using the mac-limit slot slot maximum max rate interval action forward alarm enable command to limit the maximum number of MAC addresses that can be learned and discard excess packets when the maximum number is reached, the device directly forwards all subsequent packets when the number of MAC addresses learned from packets on the specified board exceeds the value specified in max, without adding their MAC addresses to the MAC address table.

Possible Causes

A slot-based MAC address learning limit rule was configured to limit the maximum number of MAC addresses that can be learned and report an alarm when the maximum number was reached or exceeded. In addition, the number of MAC addresses dynamically learned from packets on the board reached or exceeded the specified maximum number.

Procedure

  1. Run any of the following commands:

    • Run the mac-limit slot slot maximum max rate interval command in the system view to enlarge the number of MAC addresses that can be learned.
    • Run the undo mac-address command in the system view to delete some or all MAC addresses.

    Then, check whether the alarm is cleared.

    • If the alarm is cleared, go to Step 3.

    • If the alarm persists, go to Step 2.

  2. Collect alarm information and configuration information, and then contact technical support personnel.
  3. End.

Possible Causes

A slot-based MAC address learning limit rule was configured to limit the maximum number of MAC addresses that can be learned and report an alarm when the maximum number was reached or exceeded. In addition, the number of MAC addresses dynamically learned from packets on the board fell below the specified maximum number.

Procedure
