CISCO-MAC-NOTIFICATION-MIB.mib object view, vendor Cisco

Introduction

Most network devices and programs ship with so-called MIB files to describe the parameters and meanings (i.e.: friendly names) which are available for monitoring via SNMP.
ActiveXperts Network Monitor 2019 can import vendor-specific MIB files, so it can be used to monitor specific OID's (Object Identifiers). This way, you can monitor your devices, computers, etc. by selecting your relevant OID's by name.

ActiveXperts Network Monitor 2019 can import MIB file CISCO-MAC-NOTIFICATION-MIB and use it to monitor vendor specific OID's.

CISCO-MAC-NOTIFICATION-MIB file content

Object view of CISCO-MAC-NOTIFICATION-MIB:

Scalar Object
cmnGlobalFeatureEnabled .1.3.6.1.4.1.9.9.215.1.1.1
Indicates 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 cmnIfConfigTable.
cmnNotificationInterval .1.3.6.1.4.1.9.9.215.1.1.2
This object specifies the maximum interval of time between cmnMacChangedNotifications being generated by the device. If the value of cmnNotificationsEnabled is true(1), the device will send out the generated cmnMacChangedNotifications and archive the MAC change notification events in the cmnHistoryTable. If the value of cmnNotificationEnabled is false(2), the device will not send out the generated cmnMacChangedNotifications but it will archive these events in the cmnHistoryTable. If the value of this object is equal to 0, the device will generate cmnMacChangedNotifications and archive the MAC change notification events in the cmnHistoryTable 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 cmnMacChangedNotifications and archive the MAC change notification events in the cmnHistoryTable.
cmnMacAddressesLearnt .1.3.6.1.4.1.9.9.215.1.1.3
Indicates the number of MAC addresses learnt by the device.
cmnMacAddressesRemoved .1.3.6.1.4.1.9.9.215.1.1.4
Indicates the number of MAC addresses removed from the forwarding database.
cmnNotificationsEnabled .1.3.6.1.4.1.9.9.215.1.1.5
Indicates whether cmnMacChangedNotification 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 cmnHistoryTable.
cmnNotificationsSent .1.3.6.1.4.1.9.9.215.1.1.6
Indicates the number of cmnMacChangedNotifications sent out by the device.
cmnHistTableMaxLength .1.3.6.1.4.1.9.9.215.1.1.7

Indicates whether this interface is enabled to send cmnMacChangedNotification when it learns a new MAC address. This variable has no effect when the value of cmnGlobalFeatureEnabled object is false(2). Setting this object to true(1) enables the sending of cmnMacChangedNotification when this interface learns a new MAC address. Setting this object to false(2) disables the sending of cmnMacChangedNotification when this interface learns a new MAC address.

This variable has no effect when the value of cmnGlobalFeatureEnabled object is false(2). Setting this object to true(1) enables the sending of cmnMacChangedNotification 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 cmnMacChangedNotification when a MAC address which this interface learnt previously is removed from the forwarding table.

This table enables or disables the generation of notification at each interface when MAC address is learnt or removed.
cmnUtilizationTable .1.3.6.1.4.1.9.9.215.1.4.5

Trap
cmnMacChangedNotification .1.3.6.1.4.1.9.9.215.2.0.1
This 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 cmnNotificationInterval object. If there are more MAC addresses information than can fit into one cmmHistTrapContent object, then multiple notifications will be generated.
