DHCPv6 Snooping
– 328 –
VLAN according to the default status, or as specifically configured for an
interface with the
no ipv6 dhcp snooping trust
command.
◆
When an untrusted port is changed to a trusted port, all the dynamic DHCPv6
snooping bindings associated with this port are removed.
◆
Additional considerations when the switch itself is a DHCPv6 client
– The port(s)
through which it submits a client request to the DHCPv6 server must be
configured as trusted.
Example
This example sets port 5 to untrusted.
Console(config)#interface ethernet 1/5
Console(config-if)#no ipv6 dhcp snooping trust
Console(config-if)#
