# MAC Notification Threshold

## Navigation

Device > Configure > MAC Notification > MAC Notification Threshold...

The following information appears:

- MAC Threshold Notification Feature Enabled (cmnMACThresholdFeatureEnabled)

- Limit in % (cmnMACThresholdLimit)

- Interval (cmnMACThresholdInterval)

- Notification (cmnMACThresholdNotifEnabled)

> When the value of cmnMACThresholdFeatureEnabled is true(1), a table which displays the following objects appears:

- Entity (entPhyDescr)

- No Of Entries (cmnUtilizationEntries)

- Utilization in % (cmnUtilizationUtilization)

- Time (cmnUtilizationTimeStamp)

> Note that the entries in this table are updated at the end of every cmnMACThresholdInterval.

### MAC Threshold Notification Feature Enabled (cmnMACThresholdFeatureEnabled)

When this object is set to true(1), the MAC threshold notification feature is currently running on the device.

### Limit in % (cmnMACThresholdLimit)

Indicates the threshold limit percentage of forwarding table utilization.

### Interval (cmnMACThresholdInterval)

The interval at which forwarding table utilization is compared against cmnMACThresholdLimit.

### Notification (cmnMACThresholdNotifEnabled)

Specifies whether cmnMacMACThresholdNotification notifications are sent when the forwarding table utilization percentage exceeds or equals the value set for cmnMACThresholdLimit.

### Entity (entPhyDescr)

Textual description of this physical entity. This object should identify the manufacturer of the physical entity and be set to a distinct value for each version or model of the physical entity.

### No Of Entries (cmnUtilizationEntries)

Number of entries present in the forwarding table for the given entPhysicalIndex calculated at the end of cmnMACThresholdInterval.

### Utilization in % (cmnUtilizationUtilization)

Utilization percentage of the forwarding table for the given entPhysicalIndex calculated at the end of cmnMACThresholdInterval.

### Time (cmnUtilizationTimeStamp)

Value of sysUptime when cmnUtilizationUtilization was updated.
