LAN Clients
The LAN clients feature allows you to see all the hosts on the LAN segment. Each host is
qualified to be either dynamic (host obtained a lease from this 6381 RG) or static (host has a
manually-configured IP address).
You can add a static IP address (belonging to the 6381 RG’s LAN subnet) using the
LAN Clients
page. Any existing static entry falling within the DHCP server's range can be deleted and the IP
address is made available for future allocation.
Dynamic clients will only be displayed in the list only when the DHCP server is running.
