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adapters 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.
