Build L2 Topology Option
You can specify how the L2 topology is calculated:
| Field/Check Box | Default Value | Description |
| Filter DHCP Entries | Disabled | If enabled, the system filters out the outdated DHCP entries and only keeps the latest IP addresses when building L2 topology. |
| Use all devices' MAC Table to calculate the Switch Port and Possible Switch Port in One-IP Table | Enabled | If enabled, the system will use all devices' MAC Table to calculate the Switch Port and Possible Switch Port in One-IP Table. |
| Only save One-IP Table entries that have values in any of the Switch Port, Possible Switch Port, and DNS Name | Enabled | If enabled, the system only saves entries with switch ports, possible switch ports or DNS names in One-IP table. It helps decrease the storage size and increase the query efficiency of the One-IP table. |
|
Note: Any changes to the settings will take effect from the next L2 topology calculation. |
