DHCP Relay Interface Settings
This window is used to set up a server, by IP address, for relaying DHCP information to the Switch. The user may

at the bottom of the
window, once the user clicks the

Switch. Entries may be deleted by clicking the corresponding

the interface level has higher priority. In this case, the DHCP server configured on the VLAN will not be used to
forward the DHCP packets.
