DESCRIPTION
Select this check box to enable DHCPv4 relay.
Enter the IP address of a DHCPv4 server in dotted decimal notation.
Select a pre-defined DHCPv4 option 82 profile that the Switch applies to all ports. 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 Cancel to begin configuring this screen afresh.
DESCRIPTION
Enter the number of port(s) to which you want to apply the specified DHCP option 82
profile.
You can enter multiple ports separated by (no space) comma (,) or hyphen (-). For
example, enter "3-5" for ports 3, 4, and 5. Enter "3,5,7" for ports 3, 5, and 7.
Select a pre-defined DHCP option 82 profile that the Switch applies to the specified port(s).
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.
The profile you select here has priority over the one you select in the DHCP > DHCPv4 >
Global screen.
