1. From the Web Management Interface, click on System, then ARP. The ARP Tables screen
appears. You can view, delete, or add new ARP table entries from this screen.
Configurable Gateway ARP Refresh Interval
The NSE will periodically refresh its ARP cache entry for the gateway IP. When gateway
redundancy is implemented via the use of multiple gateway devices with the same IP address,
the periodic refresh enables the NSE to quickly discover the new MAC address of the gateway.
You can set the refresh frequency on the Location page. The frequency must be between 30 and
600 seconds. 600 seconds is half of the ARP cache refresh interval, so the ARP entry can never
expire.
