Defining DHCP Snooping Properties

The

DHCP Snooping Properties Page

contains parameters for enabling DHCP Snooping on the device. To define

DHCP Snooping on the device:

Click

System > Management Security > DHCP Snooping > Properties

. The

Page

opens:

Figure 55: DHCP Snooping Properties Page

The

DHCP Snooping Properties Page

contains the following fields:

•

DHCP Snooping Status

— Indicates if DHCP Snooping is enabled on the device. The possible field values

are:

–

Enable — Enables DHCP Snooping on the device.

–

Disable

— Disables DHCP Snooping on the device. This is the default value.

•

Pass Through Option 82

— Indicates if DHCP Option 82 with data insertion is enabled on the device. The

possible field values are:

–

Enable

— If DHCP Option 82 with data insertion is enabled, the DHCP relay agent or DHCP Snooping

switch can insert information into the DHCP DISCOVER message.

he Relay agent information option

specifies the port number from which the client’s packet was received.

–

Disable

— Disables DHCP Option 82 with data insertion on the device. This is the default value.

•

Verify MAC Address

— Indicates if MAC addresses are verified. The possible field values are:

–

Enable

— Verifies that an untrusted port source MAC address matches the client’s MAC address.

–

Disable

— Disables verifying that an untrusted port source MAC address matches the client’s MAC

address. This is the default value.
