Configuring an IP helper address To forward a client broadcast request for a UDP application when the client and server are on different networks, you must configure a helper address on the interface connected to the client.
DHCP Auto-Provisioning Enhancements Auto-provisioning allows DHCP clients to boot up with the latest flash image and configuration without manual intervention. DHCP auto-provisioning enhancements have been introduced in FastIron 08.0.80 so that you can override the default behavior. The current behavior is that the ICX device (DHCP client) is forced to download the application image type based on the current version of the device.
Dynamic DHCP options configuration processing The system can differentiate between manually configured DHCP options and DHCP options that were obtained dynamically from the server. Manually configured DHCP options are retained even when the dynamic IP address is released.
Discovery of SZ based on DHCP Option 43 Beginning with SmartZone release 5.0, the administrator can monitor and manage switches and routers in the ICX 7000 series switches running FastIron version 08.0.80 or above. ICX (the DHCP client) can parse the value of DHCP option 43 containing SZ IP addresses received from the DHCP server and connect to Smartzone.
