DHCPv6 Snooping
– 376 –
Set all interfaces connected to DHCv6 servers within the local network or fire
wall to trusted, and all other interfaces outside the local network or fire wall to
untrusted.
When DHCPv6 snooping is enabled globally and enabled on a VLAN, DHCPv6
packet filtering will be performed on any untrusted ports within the VLAN
according to the default status, or as specifically configured for an interface.
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.
Parameters

Interface – Port or trunk identifier.
