64.5.2 DHCP Smart Relay Configuration Example

domains.

DESCRIPTION
Port
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/
1-1/24,2/28 for ports 1 to 24 for the Switch in slot 1 and port 28 for the Switch in slot 2, for example.
Option 82 Profile
Select a pre-defined DHCP option 82 profile that the Switch applies to the specified 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.
The profile you select here has priority over the one you select in the
