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.
