LABEL

DESCRIPTION

VLAN Search by VID Enter the VLAN ID you want to manage. Use a comma (,) to separate individual VLANs or a 

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

Search

Click this to display the specified range of VLANs in the section below.

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: The Switch will drop all DHCP requests if you enable DHCP snooping and 

there are no trusted ports.

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.

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.
