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.
Click this to create a new entry or to update an existing one.
This saves 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.
