LABEL DESCRIPTION
VID Enter the ID number of the VLAN you want to configure here.
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)
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 (see Section 26.6 on page 231).
The profile you select here has priority over the one you select in the DHCP Snooping >
Configure > VLAN screen.
