Synchronization#

EtherLyzer maintains synchronized local copies of supported IEEE registry datasets.

Manual synchronization#

Synchronize the local registry database manually with:

etherlyzer sync

Example output:

Synchronizing IEEE registries...

Synchronization completed in 2.41 seconds.

EtherLyzer can also synchronize registry data automatically when the local datasets exceed the configured maximum age.

The synchronization interval is controlled by DB_UPDATE_INTERVAL_HOURS.

See Configuration for configuration details.

Once the IEEE registry datasets have been synchronized locally, identifier lookups are performed against the local database.

This means EtherLyzer does not need to query an external MAC-address lookup service during normal lookup operations.

Internet access is only required when registry data needs to be synchronized.

For information about the local registry database, see Registry Database.
