DESCRIPTION
Port
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.
Option 82 Profile 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.
