If one or more of the Data Domain system Ethernet interfaces is 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 and
eth3 are for additional fiber or copper Ethernet interfaces. See Figure 34 for ethernet interface
locations.
