Further Operations

This section introduces other operations on the One-IP Table.

• Resolve MAC Address with Multiple IP Addresses
• Only Save Entries with Switch port Values
• Global Data Clean

Resolve MAC Address with Multiple IP Addresses 

Many terminal devices in the network automatically obtain IP addresses through DHCP. For example, when an engineer’s laptop was moved from building A to building B, the IP address may be retrieved again, but the MAC address of the laptop remains the same. As a result, multiple IP addresses might be on one MAC address in the One-IP table.

To automatically use the latest IP address entry and remove the outdated ones from the One-IP Table, you can filter the DHCP entries: Go to Domain Management >   >Advanced Settings >Build L2 Topology Options, and then check the Filter DHCP Entries box.

Provide Information about Possible Switch port and Gateway

Certain IP/MAC entries in the One IP table do not have a corresponding switch port because of the NDP neighbor in the domain. Due to this, users cannot determine the connected switch port and hence cannot locate the IP/MAC in their network. To solve this issue, two columns, Gateway and Possible Switch Port are added into One IP table to provide corresponding information. 

Global Data Clean

As the network system is constantly changing, some IP addresses become invalid, and the redundant entries of these IP addresses remain in the One-IP table. The NetBrain System supports removing old One-IP Table entries by setting the auto-clean rules for the One-IP table data in your domain.

To customize the auto-clean rules for the One-IP table data in your domain, do the following:

1. Log into the Domain Management Page.
2. On the Domain Management Page, select Domain Settings > Global Data Clean Settings from the quick access toolbar.
3. On the Global Data Clean Settings tab, customize the auto-clean rules on the One-IP Table Entries.
   
   
4. Click Save.
