Setup the Prestige as a DHCP Relay
•What is DHCP Relay?
DHCP stands for Dynamic Host Configuration Protocol. In addition to the DHCP server feature, the P2602
supports the DHCP relay function. When it is configured as DHCP server, it assigns the IP addresses to the
LAN clients. When it is configured as DHCP relay, it is reponsable for forwarding the requests and responses
negotiating between the DHCP clients and the server. See figure 1.
