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 a range.
For example, enter "3-5" for ports 3, 4, and 5. Enter "3,5,7" for ports 3, 5, and 7.
In stacking mode, the first number represents the slot and the second the port number. Enter
1/1-1/24,2/23 for ports 1 to 24 for the Switch in slot 1 and port 23 for the Switch in slot 2, for
example.
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.
Note: The profile you select here has priority over the one you select in the DHCP >
DHCPv4 > Global screen.

changes to the non-volatile memory when you are done configuring.
