MAC-NOTIFICATION-MIB
AI MIB Summary
The MAC-NOTIFICATION-MIB configures and manages the MAC address learning and removal events within the forwarding database of network switches and bridges. It enables monitoring systems to receive asynchronous traps or notifications specifically tracking dynamic MAC address table changes to detect topology shifts or security anomalies.
This MIB module is for configuration of the MAC notification feature. MAC notification is a mechanism to inform monitoring devices when there are MAC addresses learnt or removed from the forwarding database of the monitored devices.

macNotificationMIBThis MIB module is for configuration of the MAC notification
feature. MAC notification is a mechanism to inform monitoring
devices when there are MAC addresses learnt or removed from
the forwarding database of the monitored devices. MODULE-IDENTITY .1.3.6.1.4.1.13464.1.2.3.3.1 |
macNotificationMIBObjects OBJECT IDENTIFIER .1.3.6.1.4.1.13464.1.2.3.3.1.1 |
mnGlobalObjects OBJECT IDENTIFIER .1.3.6.1.4.1.13464.1.2.3.3.1.1.1 |
mnGlobalFeatureEnabledIndicates whether the MAC notification feature is currently
running in the device.
Setting this object to false(2) disables the MAC notification
feature globally thus disabling the feature at each interface.
Setting this object to true(1) will start the MAC notification
feature running in the device. If the feature is already
running, setting to true(1) has no effect. Once the MAC
notification is enabled, whether the feature is running at each
interface is controlled by the mnIfConfigTable.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.1 |
mnNotificationIntervalThis object specifies the maximum interval of time between
mnMacChangedNotifications being generated by the device.
If the value of mnNotificationsEnabled is true(1), the
device will send out the generated mnMacChangedNotifications
and archive the MAC change notification events in the
mnHistoryTable. If the value of mnNotificationsEnabled is
false(2), the device will not send out the generated
mnMacChangedNotifications but it will archive these events
in the mnHistoryTable.
If the value of this object is equal to 0, the device will
generate mnMacChangedNotifications and archive the MAC
change notification events in the mnHistoryTable as soon as
there is MAC address learnt or removed by the device.
If the value of this object is greater than 0, the device will
wait for a period of time equal to the value of this object
before generate the mnMacChangedNotifications and archive
the MAC change notification events in the mnHistoryTable.rw Unsigned32 .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.2 |
mnMacAddressesLearntIndicates the number of MAC addresses learnt by the
device.ro Counter32 .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.3 |
mnMacAddressesRemovedIndicates the number of MAC addresses removed from the
forwarding database.ro Counter32 .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.4 |
mnNotificationsEnabledIndicates whether mnMacChangedNotification notifications
will or will not be sent when there are MAC addresses
learnt or removed from the device's forwarding database.
Disabling notifications does not prevent the MAC address
info from being added to the mnHistoryTable.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.5 |
mnNotificationsSentIndicates the number of mnMacChangedNotifications sent out
by the device.ro Counter32 .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.6 |
mnHistTableMaxLengthThe upper limit on the number of entries that the
mnHistoryTable may contain. A value of 0 will
prevent any history from being retained. When this
table is full, the oldest entry will be deleted and
a new one will be created.rw Unsigned32 .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.7 |
mnHistoryTableThis table will archive the MAC change notification events
generated by this device. The MAC change notification
events are archived here even if mnMacChangesNotifications
are not actually sent. SEQUENCE OF MnHistoryEntry .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.8 |
mnHistoryEntryA MAC change notification message that was previously
generated by this device. Each entry is indexed by a message
index. MnHistoryEntry .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.8.1 |
mnHistIndexAn index that uniquely identifies a MAC change notification
event previously generated by the device. This index starts at
1 and increases by one when a MAC change notification is
generated. When it reaches the maximum value, the agent wraps
the value back to 1. Unsigned32 .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.8.1.1 |
mnHistMacChangedMsgThis object contains the information of a MAC change
notification event. It consists of several tuples packed
together in the format of '<tuple1><tuple2>...'.
Each tuple consist of 11 octets in the format of
'<operation><VLAN><MAC><dot1dBasePort>' where
<operation> is of size 1 octet and supports the following values
0 - End of MIB object.
1 - MAC learnt.
2 - MAC removed.
<VLAN> is VLAN number of the VLAN which the MAC address is
belonged to and has size of 2 octet.
<MAC> is the Layer2 Mac Address and has size of 6 octets.
<dot1dBasePort> is the value of dot1dBasePort for the
interface from which the MAC address is learnt and has size
of 2 octets.ro OCTET STRING .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.8.1.2 |
mnHistTimestampThe value of sysUpTime when the mnMacChangedNotification
containing the information denoted by the mnHistMacChangedMsg
object in this entry was generated.ro TimeStamp (SNMPv2-TC) .1.3.6.1.4.1.13464.1.2.3.3.1.1.1.8.1.3 |

mnIfConfigTableThis table enables or disables the generation of notification
at each interface when MAC address is learnt or removed. SEQUENCE OF MnIfConfigEntry .1.3.6.1.4.1.13464.1.2.3.3.1.1.2.1 |
mnIfConfigEntryEach entry contains the configuration for enabling the
MAC notification at each interface that supports this
feature. MnIfConfigEntry .1.3.6.1.4.1.13464.1.2.3.3.1.1.2.1.1 |
mnMacAddrLearntEnableIndicates whether this interface is enabled to send
mnMacChangedNotification when it learns a new MAC address. This
variable has no effect when the value of mnGlobalFeatureEnabled
object is false(2).
Setting this object to true(1) enables the sending of
mnMacChangedNotification when this interface learns a
new MAC address.
Setting this object to false(2) disables the sending
of mnMacChangedNotification when this interface learns
a new MAC address.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.13464.1.2.3.3.1.1.2.1.1.1 |
mnMacAddrRemovedEnableIndicates whether this interface is enabled to send
mnMacChangedNotification when a MAC address which it learnt
previously is removed from the forwarding table. This variable
has no effect when the value of mnGlobalFeatureEnabled object
is false(2).
Setting this object to true(1) enables the sending of
mnMacChangedNotification when a MAC address which this
interface learnt previously is removed from the forwarding
table.
Setting this object to false(2) disables the sending of
mnMacChangedNotification when a MAC address which this
interface learnt previously is removed from the forwarding
table.rw TruthValue (SNMPv2-TC) .1.3.6.1.4.1.13464.1.2.3.3.1.1.2.1.1.2 |

mnMacChangedNotificationThis notification is generated when there is enough MAC
address information to fully occupy a maximum size SNMP trap
message. This notification is also generated when there
is at least one MAC address changed or removed and the amount
of time elapsed from the previous notification is greater
than the maximum wait time denoted by
mnNotificationInterval object.
If there are more MAC addresses information than can fit into
one mmHistTrapContent object, then multiple notifications
will be generated. NOTIFICATION-TYPE .1.3.6.1.4.1.13464.1.2.3.3.1.2.0.1 |
