JUNIPER-L2ALD-MIB
Updated May 31, 2016AI MIB Summary
The JUNIPER-L2ALD-MIB module enables monitoring of Layer 2 Address Learning Daemon (L2ALD) events and trap notifications on Juniper Networks devices to track MAC address table changes, aging, and learning failures. It specifically facilitates the detection of L2ALD state transitions and anomalies within the switching fabric to support rapid troubleshooting of MAC address table integrity.

jnxl2aldNotification OBJECT IDENTIFIER .1.3.6.1.4.1.2636.3.48.1.0 |
jnxl2aldRoutingInstMacLimitThis notification is generated when the MAC limit for
given routing instance (jnxl2aldRoutingInst) is reached.
This trap is send only once we exceed the limit value. NOTIFICATION-TYPE .1.3.6.1.4.1.2636.3.48.1.0.1 |
jnxl2aldInterfaceMacLimitThis notification is generated when the MAC limit for
the given physical interface (jnxl2aldInterfaceMacLimit) is reached.
This trap is send only once we exceed the limit value. NOTIFICATION-TYPE .1.3.6.1.4.1.2636.3.48.1.0.2 |
jnxl2aldGlobalMacLimitThis notification is generated when the MAC limit for
the entire system is reached.
This trap is send only once we exceed the limit value. NOTIFICATION-TYPE .1.3.6.1.4.1.2636.3.48.1.0.3 |
jnxl2aldMacMoveThresholdThis notification is generated when a mac move reaches threshold.
The given interface (ifDescr) will be blocked for the Bridge
Domain(jnxl2aldIntfBridgeDomain). This trap is send only once when
mac move count exceeds the threshold for the Mac(jnxl2aldMacAdress). NOTIFICATION-TYPE .1.3.6.1.4.1.2636.3.48.1.0.4 |
jnxL2aldMacChangedNotificationThis 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
jnxNotificationInterval object.
If there are more MAC addresses information than can fit into
one cmmHistTrapContent object, then multiple notifications
will be generated. NOTIFICATION-TYPE .1.3.6.1.4.1.2636.3.48.1.0.5 |
jnxl2aldMacPinningdiscardThis notification is generated for discarding packets in a bridge domain over an
IFL for MACs when learned over MAC pinning enabled interface and same MACs are
also seen over any other interfaces in the same bridge domain.
This trap is generated in configured interval of time when packets are discarded
over an IFL continuously. NOTIFICATION-TYPE .1.3.6.1.4.1.2636.3.48.1.0.6 |

jnxL2aldMacGlobalFeatureEnabledIndicates whether the MAC notification feature is currently
running in the device.
Setting this object to false(2) disables the MAC notification
feature globally.
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.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.2636.3.48.1.2.1.1 |
jnxL2aldMacNotificationIntervalThis object specifies the maximum interval of time between
jnxL2aldMacChangedNotifications being generated by the device.
If the value of jnxNotificationsEnabled is true(1), the
device will send out the generated jnxL2aldMacChangedNotifications
and archive the MAC change notification events in the
jnxMacHistoryTable. If the value of jnxNotificationEnabled is
false(2), the device will not send out the generated
jnxL2aldMacChangedNotifications but it will archive these events
in the jnxMacHistoryTable.
If the value of this object is equal to 0, the device will
generate jnxL2aldMacChangedNotifications and archive the MAC
change notification events in the jnxMacHistoryTable 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 jnxL2aldMacChangedNotifications and archive
the MAC change notification events in the jnxMacHistoryTable.ro Unsigned32 .1.3.6.1.4.1.2636.3.48.1.2.1.2 |

device.ro Counter64 .1.3.6.1.4.1.2636.3.48.1.2.1.3 |

forwarding database.ro Counter64 .1.3.6.1.4.1.2636.3.48.1.2.1.4 |
jnxL2aldMacNotificationsEnabledIndicates whether jnxL2aldMacChangedNotification 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 jnxMacHistoryTable.ro TruthValue (SNMPv2-TC) .1.3.6.1.4.1.2636.3.48.1.2.1.5 |

jnxMacHistoryTable 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.ro Unsigned32 .1.3.6.1.4.1.2636.3.48.1.2.1.7 |
jnxL2aldMacHistoryTableThis table will archive the MAC change notification events
generated by this device. The MAC change notification
events are archived here even if jnxMacChangesNotifications
are not actually sent. SEQUENCE OF JnxL2aldMacHistoryEntry .1.3.6.1.4.1.2636.3.48.1.2.1.8 |

generated by this device. Each entry is indexed by a message
index. JnxL2aldMacHistoryEntry .1.3.6.1.4.1.2636.3.48.1.2.1.8.1 |
jnxL2aldHistIndexAn 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 .1.3.6.1.4.1.2636.3.48.1.2.1.8.1.1 |
jnxL2aldHistMacChangedMsgThis 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 13 octets in the format of
'<operation><VLAN INDEX><MAC><dot1dBasePort><VLAN TAG>' where
<operation> is of size 1 octet and supports the following values
0 - End of MIB object.
1 - MAC learnt.
2 - MAC removed.
3 - MAC updated.
<VLAN INDEX> is the index 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.
<VLAN TAG> is the tag of the VLAN which the MAC address is
belonged to and has size of 2 octet.ro OCTET STRING .1.3.6.1.4.1.2636.3.48.1.2.1.8.1.2 |
