Configuring basic DHCPv6 snooping

Follow these guidelines when you configure basic DHCPv6 snooping:
• To make sure DHCPv6 clients can obtain valid IPv6 addresses, specify the ports connected to
authorized DHCPv6 servers as trusted ports. The trusted ports and the ports connected to DHCPv6
clients must be in the same VLAN.
If you configure DHCPv6 snooping settings on a Layer 2 Ethernet interface that is a member port of
•
a Layer 2 aggregate interface, the settings do not take effect unless the interface is removed from
the aggregation group.
