3.6 DHCP
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 Prestige
as a DHCP server or disable it. When configured as a server, the Prestige provides the TCP/IP
configuration for the clients. If DHCP service is disabled, you must have another DHCP server
on your LAN, or else the computer must be manually configured.
3.6.1 IP Pool Setup
When you set the Prestige as a DHCP server, you can use the default DHCP client IP address
pool setting. The default address pool has 20 IP addresses starting from 192.168.1.2 to
192.168.1.21. This configuration leaves the other IP addresses for other server computers, for
instance, servers for mail, FTP, TFTP, web, etc., that you may have.
3.6.2 DNS Servers
There are two places where you can configure DNS setup on the Prestige.
1 Use the WAN DNS screen to configure the Prestige to use a DNS server to resolve
domain names for Prestige system features like VPN, DDNS and the time server.
2 Use the LAN DHCP Server screen to configure the DNS server information that the
Prestige sends to the DHCP client devices on the LAN.
3.6.3 DHCP Setup
To configure DHCP settings on the LAN, click Configuration, LAN and DHCP Server to
display the screen as shown.
Set High
Priority TOS
This field is applicable when you enable TOS priority control.
IEEE 802.1p defines up to 8 separate traffic types by inserting a tag into a MAC-layer
frame that contains bits to define class of service. Frames without an explicit priority
tag are given the default priority of the ingress (incoming) port.
Select the high priority level(s). The Prestige will first send packets with matching
priority level(s).
