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 fire wall.
When DHCP snooping is 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 fire
◆
wall to trusted state. Set all other ports outside the local network or fire
wall to untrusted state.
