DHCP Relay 123
DHCP Relay
HPE OfficeConnect 1920S switches can be used to relay packets between a DHCP client and server
on different subnets. The switch acts as an L3 relay agent and must have an IP interface on the client
subnets and, if it does not have an IP interface on the server’s subnet, it should be able to route traffic
toward the server’s subnet.
DHCP Relay Global Configuration
Use the DHCP Relay Global Configuration page to enable the DHCP relay feature on the switch and to
view and configure information about DHCP servers where packets should be relayed.
To display the DHCP Relay Global Configuration page, click Routing > DHCP Relay in the navigation
pane, and ensure that the Global tab is selected.
