Syntax
dhcp-snooping trust
undo dhcp-snooping trust
View
Ethernet port view
Parameters
None
Description
Use the dhcp-snooping trust command to set an Ethernet port to a DHCP-snooping
trusted port.
Use the undo dhcp-snooping trust command to restore an Ethernet port to a
DHCP-snooping untrusted port.
By default, with the DHCP snooping enabled, all the ports of a switch are untrusted
ports.
Note that: After DHCP snooping is enabled, you need to specify the port connected to a
valid DHCP server as trusted to ensure that DHCP clients can obtain valid IP addresses.
The trusted port and the ports connected to DHCP clients must be in the same VLAN.
