Getting To Know Your ZyAIR 1-3
DHCP Support
DHCP (Dynamic Host Configuration Protocol) allows the individual clients (computers) to obtain the
TCP/IP configuration at start-up from a centralized DHCP server. The ZyAIR has built-in DHCP server
capability enabled by default. It can assign IP addresses, an IP default gateway and DNS servers to DHCP
clients. The ZyAIR also acts as a surrogate DHCP server (DHCP Relay) where it relays IP address
assignment from the actual real DHCP server to the clients.
Multicast
Traditionally, IP packets are transmitted in two ways - unicast or broadcast. Multicast is a third way to
deliver IP packets to a group of hosts. IGMP (Internet Group Management Protocol) is the protocol used to
support multicast groups. The latest version is version 2 (see RFC 2236). The ZyAIR supports versions 1
and 2.
