DHCP Snooping Global Configuration

Use the DHCP Snooping Global Configuration page to enable or disable the DHCP Snooping 
feature on the switch. 

To access the DHCP Snooping Configuration page, click System

> Services > DHCP 

Snooping > Global Configuration.

To configure global DHCP Snooping settings:

In the Admin Mode field, select Enable or Disable to turn the DHCP Snooping feature 
on or off. DHCP snooping is globally disabled by default.

In the MAC Address Validation field, select Enable to allow the switch to validate the sender 
MAC address for DHCP snooping. If Disable is selected, the switch will not check the 
source MAC address. MAC address validation is enabled by default.

Configure the DHCP snooping mode for VLANs. Enter the VLAN ID and specify whether to 
enable or disable DHCP snooping:

Enable. When a DHCP packet is received on a routing VLAN, the DHCP snooping 

application applies its filtering rules and updates the bindings database. If a client 
message passes filtering rules, the message is placed into the software forwarding 
path, where it may be processed by the DHCP relay agent, the local DHCP server, or 
forwarded as an IP packet.

Disable. Traffic in the VLAN is not snooped for DHCP massages.

Click Apply to apply the change to the system. The changes take effect immediately.

Click Cancel to cancel the configuration on the screen and reset the data on the screen to 
the latest value of the switch.
