28.13 ip dhcp snooping trust

Command:

ipv6 dhcp snooping trust

no ipv6 dhcp snooping trust

Function:

Set the port to the trusted port. The no command sets the port to non-trusted port.

Parameters:

None

Command Mode:

Port mode

Default Settings:

By default, the port is non-trusted port.

Usage Guide:

When a port turns into a trusted port from a non-trusted port, the original security policy of the port

will be deleted that means clear all blackhole MAC or undo the shutdown of this port. At the same

time, it allows the DHCPv6 responding packets of this port to be forwarded. When a port turns into a

non-trusted port from a trusted port, forbid the DHCPv6 responding packets to be forwarded and

drop them.

Example:

Set the port as the trusted port.

switch(config-if-ethernet1/1)# ipv6 dhcp snooping trust
