4.11.16.4 DHCP Snooping Port Configuration 

Configures switch ports as trusted or untrusted. 

 

Command Usage   

•

  A trusted interface is an interface that is configured to receive only messages from within the network. An untrusted interface 

is an interface that is configured to receive messages from outside the network or firewall.   

•

  When DHCP snooping enabled both globally and on a VLAN, DHCP packet filtering will be performed on any untrusted ports 

within the VLAN.   

•

  When an untrusted port is changed to a trusted port, all the dynamic DHCP snooping bindings associated with this port are 

removed.   

•

  Set all ports connected to DHCP servers within the local network or firewall to trusted state. Set all other ports outside the 

local network or firewall to untrusted state.
