DHCP Table
DHCP (Dynamic Host Configuration Protocol, RFC 2131 and RFC 2132) allows individual clients to
obtain TCP/IP configuration at start-up from a server. You can configure the NBG’s LAN as a DHCP
server or disable it. When configured as a server, the NBG provides the TCP/IP configuration for the
clients. If DHCP service is disabled, you must have another DHCP server on that network, or else
the computer must be manually configured.
Click the
DHCP Table (Details...)
hyperlink in the
Status
screen. Read-only information here
relates to your DHCP status. The DHCP table shows current DHCP client information (including
IP
Address
,
Host
Name
and
MAC Address
) of all network clients using the NBG’s DHCP server.
