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.

If a slot-based MAC address learning limit rule is configured using the mac-limit maximum 10 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 maximum 10 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.
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.
Then, check whether the alarm is cleared.
If the alarm is cleared, go to Step 3.
If the alarm persists, go to Step 2.
