Configuration > DHCP > DHCP Snooping 

Configure DHCP Snooping on this page.

 

DHCP Snooping is used to block an intruder on the untrusted 

switch ports when it tries to intervene by injecting a bogus DHCP reply packet to a legitimate conversation 

between the DHCP client and server. 

 

The DHCP Snooping parameters are described below. 

DHCP Snooping Mode 

Indicates the DHCP snooping mode operation. Possible modes are:  

Enabled

: Enable DHCP snooping mode operation. When DHCP snooping mode operation is 

enabled, the DHCP request messages will be forwarded to trusted ports and only allow reply packets 

from trusted ports.  

Disabled

: Disable DHCP snooping mode operation.  

Port Mode Configuration 

Indicates the DHCP snooping port mode. Possible port modes are:  

Trusted

: Configures the port as trusted source of the DHCP messages.  

Untrusted

: Configures the port as untrusted source of the DHCP messages.  

Buttons 

Save

: Click to save changes. 

Reset

: Click to undo any changes made locally and revert to previously saved values.
