individual VLANs or a dash (–) to indicates a range of VLANs. For example, “3,4” or “3–9”.

VID This field displays the VLAN ID of each VLAN in the range specified above. If you configure
the * VLAN, the settings are applied to all VLANs.
Enabled Select Yes to enable DHCP snooping on the VLAN. You still have to enable DHCP snooping
on the Switch and specify trusted ports.
Note: If DHCP is enabled and there are no trusted ports, DHCP requests will not
succeed.
Option 82 Profile Select a pre-defined DHCP option 82 profile that the Switch applies to all ports in the
specified VLANs. 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 26.3 on page 213).
Apply Click Apply to save 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.
Cancel Click this to reset the values in this screen to their last-saved values.
