1. Click Targets - Port Configuration - Network Settings.
2. Under the Custom Interfaces heading, enter the name for the private interface.
3. Enter the broadcast address.
4. Click Add.
NOTE: If DHCPis desired, the IPaddress of the virtual interface should correspond to a dynamic range on the
DHCPsettings page. Newly created interfaces will not issue DHCPaddresses until the DHCPservice is restarted.
To edit or delete a virtual interface:
1. Click Targets - Port Configuration - Network Settings.
2. Under the Modify a Virtual Interface heading, check the box next to the private interface you want to edit.
3. Make your changes.

NOTE: A user cannot enable an interface if an IPaddress is empty.
DHCP Settings
From the sidebar, click Targets - Port Configuration - DHCP Settings to view or change the default DHCP server settings.
The appliance DHCPserver is required to issue IPaddresses to UMIQadaptors and can be used to issue IPaddresses to
SPs. Adynamic range is required to issue DHCPaddresses incrementally or based on MACaddress reservations. The
DHCPserver can only operate on appliance private interface ports.
To configure DHCPsettings:
1. Click Targets - Port Configuration - DHCP  Settings.
2. Check the box to enable or disable the DHCPserver.
NOTE: If using the DHCPrelay option, new firewall rules will need to be created for the interface that will receive the
DHCP request to permit FORWARD traffic to the external DHCP server host and back again.
3. DHCP leases are defined in days (default is 30).
4. Dynamic ranges can be added or deleted by clicking Add or Delete. Within each dynamic range, the gateway
field defines the range association with a virtual interface.
5. DHCPreservations are created by clicking Add or Delete in the Assignment by MACAddress heading. The
hostname is a name for the reservation. The MACAddress is the layer2 physical address of the target network
card. The Fixed Address is the IP address to be issued.
The lease bindings tell you which IP addresses have been dynamically assigned to targets. It displays the range, start and
end times, MACaddress, hostname, port number and target device type. The lease bindings can only be cleared by
deleting the dynamic range they were issued from and restarting the DHCPserver. Lease times are measured in days.
NOTE: Only one range may operate on a private interface.
Advanced settings
Within the appliance shell, the /etc/dhcpd.conf file can be edited to add DHCPscope options, such as option 6 (DNSserver)
or option 15 (DOMAIN name).
Discovery
You can discover service processors, rack PDUs or terminal servers from a variety of IPranges within routed access of the
appliance. You can specify up to 20 IP address ranges either for automatic or manual discovery. Discovered devices are
displayed in the SP Management list.
