DESCRIPTION
Enter the ID number of the VLAN you want to configure here.
Enter the number of ports 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 ports in
this VLAN. The Switch adds the information (such as slot number, port number, VLAN ID and/
or system name) specified in the profile to DHCP requests that it broadcasts to the DHCP
VLAN, if specified, or VLAN. You can specify the DHCP VLAN in the DHCP Snooping Configure
screen.
Note: The profile you select here has priority over the one you select in the DHCP
Snooping > Configure > VLAN screen.

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