DHCP Server
If one or more of the system Ethernet interfaces are to use DHCP, the DHCP server needs MAC
addresses for the interfaces and a hostname for the Data Domain system. Data Domain
recommends configuring infinite lease IP addresses for the Data Domain system interfaces. All of
the interfaces do not need to use DHCP.
If you set an interface to use DHCP and DHCP is not yet available to the interface, the Data
Domain system attempts to set up the interface without DHCP until DHCP is available. Use the
net show settings
command to display which interfaces are configured for DHCP.
The eth0 and eth1 Ethernet interfaces on the back of the Data Domain system are each labeled with
a MAC address. Eth0 and eth1 are copper 1000 Base-T gigabit interfaces. The optional eth2. eth3,
eth4 and eth5 are for additional fiber or copper Ethernet interfaces. See “System Card Interface” on
page 52 for interface locations.
