IP DHCP SNOOPING TRUST
Syntax
ip dhcp snooping trust
Parameters
None
Mode
Port Interface mode
Description
Use this command to set ports as DHCP-snooping-trusted ports. Typically,
ports connecting the switch to trusted elements in the network (towards
the core) are set as trusted ports while ports connecting untrusted network
elements are set as untrusted. Configure ports connected to DHCP
servers as trusted ports. By default, all switch ports are untrusted.
Use the no version of this command, NO IP DHCP SNOOPING TRUST, to
return a port to its default untrusted state.
