DESCRIPTION
Enter the ID number of the VLAN to which these DHCP settings apply.
Enter the IP address of a DHCP server in dotted decimal notation.
Enter the source IP address that the Switch adds to DHCP requests from clients on this VLAN
before forwarding them. If you leave this field set to 0.0.0.0, the Switch automatically sets the
source IP address of the DHCP requests to the IP address of the interface on which the packet is
received.
The source IP address helps DHCP clients obtain an appropriate IP address when you configure
multiple routing domains on a VLAN.
Select a pre-defined DHCP option 82 profile that the Switch applies to all ports in this VLAN. The
Switch adds the Circuit ID sub-option and/or Remote ID sub-option specified in the profile to
DHCP requests that it relays to a DHCP server.
Click Apply to save your changes to the Switch's run-time memory. The Switch loses these
changes if it is turned off or loses power, so use the Save link on the top navigation panel to save
your changes to the non-volatile memory when you are done configuring.
Click Clear to clear the fields to the factory defaults.
Click Cancel to not save the configuration you make and return to the last screen.
