# Interface properties update scheduler

For versions 124162 and above, it is now possible to schedule automatic update of interface properties by enabling the **Interface properties update scheduler** option (runs in the background). By default, the scheduler is enabled only for direct installations and not for customers who have upgraded from previous versions (using PPM). Please contact our support team at support@manageengine.com for further assistance on enabling this option and its properties.

**Interface properties that can be updated through the scheduler:**

| Property | Description | Default value |
|---|---|---|
| MONITORINGINTERVAL | Period at which the scheduler updates the interface properties. | 86400 |
| IFALIAS | An 'alias' name for the interface as specified by the network manager. | TRUE |
| IFDESCRIPTION | A textual string containing the product name, manufacturer name, and the version of the interface hardware/software. | TRUE |
| IFNAME | Holds the name of the interface as assigned by the local device | TRUE |
| DISPLAYNAME | Display name of the interface as shown in the Interface Snapshot page | TRUE |
| ADMINSTATUS | Admin status (ifAdminStatus) of the interface. | FALSE |
| OPERATINGSTATUS | The current operational state (ifOperStatus) of the interface. | FALSE |
| PHYSMEDIA | This variable states the physical media of this interface as reported by the SNMP agent. | FALSE |
| HCTTRAFFIC | Enable/Disable the 64-bit Traffic counter. | TRUE |
| PHYSADDRESS | Represents the media or physical-level address. | FALSE |
| IPADDRESS | Represents the IP address of the interface. | TRUE |
| IFSPEED | An estimate of the interface's current bandwidth in bits per second. | FALSE |
| IFSPEEDIN | The 'In Speed' (Bandwidth) of the Interface. | FALSE |
| IFSPEEDOUT | The 'Out Speed' (Bandwidth) of the Interface. | FALSE |

## Important Notes

1. The below four parameters should always be updated with the same **property** (propval)
   - IFALIAS
   - IFDESCRIPTION
   - IFNAME
   - DISPLAYNAME
2. The MONITOINGINTERVAL value is defined in seconds. It should not be less than 3600 seconds (1 hour).
3. Only the managed devices will be included in the schedule. Interface parameters will **NOT** be updated for devices in the 'Unmanaged' state.
4. Only the existing interfaces will be updated once the scheduler is initiated. The newly added interfaces will be included in the next schedule run based on the 'MONITORINGINTERVAL' property value.
5. The scheduler will start 24 hours after restarting either the OpManager service or the OpManager Agent service.
