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.
To configure basic DHCPv6 snooping:
Step
1. Enter system view.
2. Enable DHCPv6 snooping.
3. Enter interface view.
4. Specify the port as a trusted
port.
5. Return to system view.
6. Enter interface view.
7. (Optional.) Enable recording
of client information in
DHCPv6 snooping entries.
