Configuration Guide   5. DHCP 
5  DHCP 
DHCP is a network protocol that allows network devices to acquire IPv4 address and 
additional network configuration parameters automatically from a DHCP server.  DHCP is 
defined in RFC 2131 and the DHCP server options are defined in RFC 2132. 
MSBR supports the following DHCP operation modes: 
  DHCP Relay 
5.1  DHCP Client 
The DHCP client operation mode allows the MSBR to acquire IPv4 addresses and network 
configuration parameters automatically on its network interfaces.
